Korean Manufacturing & Supply Chain

WayvGear Korea Logo

WayvGear RF plasma systems are manufactured entirely in South Korea using the world's most advanced semiconductor and electronics supply chain. From Samsung Electro-Mechanics MLCCs to CASM's sole-source plasma bulbs — the supply chain is a strategic asset, not just a manufacturing decision.

Manufacturing location is not a neutral choice. It determines component quality, supply chain stability, regulatory compliance posture, landed cost for key markets, and — critically for a technology company — the ability to maintain tight coupling between design, manufacturing, and field performance feedback. WayvGear's Korean manufacturing position delivers advantages on all of these dimensions simultaneously.

Key Suppliers

Samsung Electro-Mechanics
MLCC Supply
Tier 1

RF power amplifier circuits are MLCC-intensive at frequencies above 1 GHz. Bypass capacitors, impedance matching networks, and coupling capacitors all demand low-ESR, high-Q MLCCs rated for the thermal and RF stress conditions of WayvGear's 2.45 GHz power stages. Samsung Electro-Mechanics is the world's second-largest MLCC manufacturer and Korea's dominant supplier — providing both the component quality required for RF performance and the supply chain reliability required for production scale.

Korean-domestic sourcing eliminates the import lead times and currency exposure associated with Murata or TDK sourcing from Japan, and the quality requirements for Samsung E-M RF-grade MLCCs are specified directly into WayvGear's board designs.

Korean PCB Fabricators
Rogers 4350B PCB Fabrication
Specialized

WayvGear's RF power stages require Rogers 4350B laminate — a PTFE-composite high-frequency PCB material with loss tangent tan δ = 0.0027 at 2.45 GHz. Standard FR-4 (tan δ ≈ 0.02) is simply not viable for 2.45 GHz matching networks: the insertion loss through even short traces on FR-4 at this frequency would eliminate most of the efficiency advantage of the LDMOS amplifier stage.

Korean PCB fabricators with established Rogers laminate processing capability provide local fabrication of these specialized boards within WayvGear's domestic supply chain, avoiding the lead time and import overhead of sourcing from offshore Rogers-qualified fabs in the US or Europe.

DB HiTek
Semiconductor Packaging
Korean Fab

DB HiTek is one of Korea's leading analog and mixed-signal semiconductor foundries, providing packaging and device processing capability for WayvGear's power semiconductor components. Korean domestic packaging capability reduces the supply chain complexity and transit time associated with offshore OSAT, and DB HiTek's focus on power and analog devices aligns with the requirements of RF power amplifier system design.

Amkor / SFA
Outsourced Semiconductor Assembly & Test (OSAT)
Korean Operations

Amkor Technology's Korean operations — headquartered in Icheon, Gyeonggi-do — provide world-class OSAT capabilities for WayvGear's semiconductor assembly requirements. Amkor's Korean infrastructure is among the world's largest and most sophisticated OSAT operations, providing packaging options from QFN through flip-chip BGA for different WayvGear component requirements. SFA Engineering provides complementary assembly capabilities for production volume flexibility.

CASM
Plasma Bulb Supply — Sole Source
Sole Supplier

CASM is the sole manufacturer of the specific plasma bulb format used in WayvGear RF plasma lighting systems. This sole-source position is not a supply chain vulnerability — it is a supply chain moat. Competitors seeking to deploy RF plasma lighting using the WayvGear technology approach cannot source equivalent plasma bulbs from alternative suppliers; CASM's position as the only manufacturer of this component configuration means that WayvGear's access to CASM supply represents a durable competitive advantage in plasma lighting manufacturing.

WayvGear's relationship with CASM, established through KJ Kim's deep Korean industry network, provides preferred access to CASM's production capacity in a supply relationship that cannot be easily replicated by new entrants attempting to commercialize competing RF plasma lighting systems.

Ampleon
LDMOS Power Amplifier Devices
Primary PA Platform

Ampleon's BLP2425M10S250P — a 250W LDMOS power transistor in a flange package rated for 2.45 GHz operation at 32V supply — is the primary power amplifier device in WayvGear's 2.45 GHz systems. The 67% drain efficiency and 65:1 VSWR ruggedness of this device define WayvGear's system efficiency and reliability specifications. NXP-qualified devices provide the 915 MHz secondary band alternative where regional frequency requirements favor this band over 2.45 GHz.

Bill of Materials

System BOM Overview

WayvGear RF plasma systems have a design-target BOM of $250–$600 per unit depending on power output configuration, cavity size, and whether the system includes integrated power supply or assumes external mains distribution. This BOM range reflects production-volume pricing for Korean-domestic component sourcing — it is not a prototype-cost estimate.

BOM CategoryKey ComponentsSupplierCost Significance
RF Power StageLDMOS PA, bias network, matching networkAmpleon / NXPHigh — PA is costliest active component
MLCCs & PassivesHigh-Q RF-grade MLCCs, resistors, inductorsSamsung E-MMedium — volume pricing available
PCB SubstrateRogers 4350B laminateKorean PCB fabsMedium — premium over FR-4, essential at 2.45 GHz
Power Supply (SMPS)100W–1kW SMPS, active PFC, worldwide mainsKorean SMPS partnersHigh — scales with output power
Plasma BulbGas-fill plasma lampCASM (sole source)Medium — unique component, sole-source pricing
Cavity & MechanicalMultimode cavity, heat spreader, enclosureKorean fabricatorsLow-medium — machined or stamped aluminum
Semiconductor PkgPA device packaging, thermal interfaceDB HiTek / AmkorLow — included in PA device cost
Control ElectronicsMicrocontroller, impedance matching control, sensorsKorean ECMLow — commodity MCU platform

The $250–$600 BOM range does not include factory overhead, assembly labor, quality testing, or packaging. Fully-loaded manufacturing cost for production volumes is estimated at a 1.5–2.0x multiplier on BOM. At the design-target BOM, WayvGear systems are cost-competitive with premium LED fixtures at equivalent power output levels while delivering substantially superior spectral quality for agricultural applications.

KORUS FTA: The Duty Advantage

0–3%
US Import Duty

The Korea-United States Free Trade Agreement (KORUS FTA), in force since 2012, provides preferential tariff treatment for qualifying Korean-origin goods entering the United States. WayvGear systems — manufactured in Korea with Korean-origin components — qualify for KORUS FTA treatment, entering the US market at 0–3% duty versus standard MFN tariff rates.

In the current global trade environment, Korean manufacturing provides structural insulation from the tariff exposure affecting Chinese-manufactured alternatives. While competing lighting products manufactured in China face substantial import duties under current US tariff schedules, WayvGear's Korean manufacturing position ensures consistent, predictable landed cost for North American distributors and licensees.

This is not a temporary policy advantage — KORUS FTA is a binding bilateral trade agreement. The duty differential is structural and durable, not subject to the executive-order tariff volatility affecting other manufacturing geographies.

Quality Standards

IEC 60335

Safety of household and similar electrical appliances. Surface temperature limits: 60°C accessible metal surfaces, 75°C accessible plastic surfaces. Verified via thermal imaging under maximum continuous operating conditions.

IEC 61000-3-2

Limits for harmonic current emissions (equipment input current up to 16A per phase). Active power factor correction in the SMPS stage ensures compliance across worldwide mains voltage ranges. Required for CE marking in Europe.

50,000-Hour Design Life

System lifetime is capacitor-limited. Electrolytic capacitors in the SMPS stage are the longest-lead wear component. Capacitor selection specifies rated ripple current derating and operating temperature limits that support 50,000-hour operational life at maximum duty cycle.

ISM Band Compliance

2.45 GHz and 915 MHz ISM bands are license-free globally under ITU Radio Regulations. Cavity shielding methods (covered by WayvGear method patents) manage radiated emissions within ISM band regulatory limits, eliminating spectrum license requirements in all target markets.

Why Korean Manufacturing?

The Korean semiconductor and electronics manufacturing ecosystem is not merely a cost-effective location choice — it is the world's most sophisticated manufacturing environment for the specific components and processes WayvGear requires. Samsung Electro-Mechanics makes the world's most advanced MLCCs. CASM makes the only plasma bulb that works in WayvGear systems. Korean PCB fabs have decades of experience with Rogers laminates for telecommunications and defense RF applications. Amkor's Korean operations represent one of the world's largest OSAT facilities.

Beyond component access, Korean manufacturing delivers process discipline, quality management infrastructure, and the engineering talent density required to maintain tight design-to-manufacturing feedback loops. For a technology company whose competitive advantage depends on manufacturing precision — RF performance is unforgiving of sloppy processes — location within Korea's electronics manufacturing ecosystem is itself a competitive asset.

And for North American customers, KORUS FTA makes Korean-origin product economically attractive in a way that no other premium manufacturing geography can currently match.
