What SemiGen does

SemiGen is a US-based RF/microwave contract manufacturer and component supplier headquartered in a 43,000 sq ft facility in Londonderry, New Hampshire. The company designs, fabricates, and tests high-reliability mixed-signal and RF/microwave hybrid assemblies, thin-film circuits, and a proprietary line of semiconductor diodes and passive components for defense primes, SATCOM and space programs, and advanced communications OEMs. Its vertically integrated stack spans wafer-level thin-film processing (including ion beam milling acquired from Ion Beam Milling, Inc. in 2018), automated and manual RF assembly, automated PCB assembly, and MIL-STD screening/testing to 50 GHz — backed by ITAR registration, ISO 9001, AS9100D, ISO 13485, and CMMC 2.0 Level 2 certification.

The product portfolio includes PIN diodes, Schottky, limiter, step recovery, beam lead, point contact, and zero-bias Schottky detector diodes, alongside thin-film attenuator pads, MIS and standoff capacitors, spiral inductors, tantalum nitride resistors, Lange/hybrid couplers, transmission lines, and filters. Service offerings cover build-to-print thin-film fabrication, automated PCB assembly for high-mix low-to-medium-volume boards (up to 44"x32"), RF/microwave performance testing, MIL-PRF-38534 / MIL-STD-750 / MIL-STD-883 upscreening (Class H, Class K, JAN, JANTX, JANTXV), design engineering, legacy module repair and refurbishment, and an e-commerce RF Supply Center for in-stock bonding tools and consumables.

SemiGen operates as a subsidiary of Naprotek, LLC (a portfolio company of Edgewater Capital Partners), serving as Naprotek's RF Assembly & Components Center of Excellence. The company sells primarily through direct enterprise RFQ engagement and engineering-driven consultative sales, targeting prime contractors and OEMs requiring ITAR compliance and MIL-STD screening. Pricing is quote-based with no public rate card. The company is led by President and CEO Tim Filteau, who also heads Naprotek Holdings, and was previously led by founder Jim Morgan. SemiGen has been recognized by BAE Systems with a Partner 2 Win Silver Tier Award (2026) for its contributions to the Electronic Systems sector.

Revenue model

1. RF/Microwave Components and Semiconductors: SemiGen manufactures and sells proprietary and custom RF/microwave semiconductor devices (diodes: PIN, Schottky, limiter, step recovery, point contact, beam lead, zero-bias) and passive components (attenuator pads, capacitors, inductor coils, resistors, transmission lines, thin film circuits). Revenue is generated through direct product sales, catalog offerings, and custom build-to-print orders.
2. Contract Manufacturing Services: SemiGen provides RF/microwave assembly, automated PCB assembly, thin film processing, wafer dicing, metallization, and ion beam milling foundry services on a contract basis. Services are priced through RFQ/quotes based on complexity, volume, and specifications.
3. Testing and Screening Services: RF/microwave performance testing and high-reliability MIL-STD screening/uptesting services are offered as standalone billable engagements for components and assemblies, supporting defense and aerospace customer quality assurance requirements.
4. RF Supply Store: The RF Supply Center (Shopify storefront) sells in-stock bonding tools, materials, and passive components for immediate delivery, generating transactional revenue and supporting supply chain augmentation for customers.
