What Microphase does

Microphase Corporation is a vertically integrated subsystem manufacturer of customized radio frequency (RF), microwave, and millimeter-wave components, devices, subsystems, and integrated modules operating across the DC to 50 GHz frequency range. Founded in 1955 and headquartered in Shelton, Connecticut, the company serves defense and aerospace primes, satellite, and homeland/global security markets with both passive and semiconductor-based solutions. Its product portfolio is organized into three core lines: Filters (lowpass, highpass, bandpass, band reject, high-power up to 2500W CW, multiplexers, switch filter banks, cavity SMT filters, SMT diplexers), Detector Log Video Amplifiers (DLVA / SDLVA) in miniature, wide dynamic range, and CW-immune variants, and Detectors (Schottky, limiter, tunnel diode back, drop-in module, RF limiters).

The company operates an AS9100D and ISO 9001:2015 certified 28,000 sq ft facility containing a Class 100,000 Clean Room, machine shop, and full suite of environmental and reliability testing equipment (vibration, thermal shock, acceleration, high-power, fine/gross leak). It is ITAR registered and serves tier-1 defense primes including BAE Systems, Lockheed Martin, Raytheon, Boeing, L3 Harris, Indra, Saab, Textron, and Aselsan, among others. The go-to-market is enterprise field sales targeting defense and aerospace customers, with technical selling led by a Sales Manager and Principal Engineers; pricing is quote-based and negotiated program-by-program for custom-engineered components.

Microphase is a wholly owned subsidiary of Gresham Worldwide, a diversified conglomerate operating across the United States, United Kingdom, and Israel. The company markets its 70-year heritage, multi-disciplinary engineering team, and reputation as the global leader in high-performance DLVAs and a pioneer in specialized communications filters. Products are stated to have been included in Apollo spacecraft hardware on display at the Smithsonian, underscoring an ultra-high reliability heritage relevant to mission-critical defense applications.
