POLYPHASE MICROWAVE INC.

Polyphase Microwave Inc. specializes in the design, development, and manufacturing of high-performance microwave and RF components for defense and aerospace applications. Leveraging deep expertise in microwave circuitry, waveguide systems, and solid-state power amplifiers, the company delivers custom solutions including filters, couplers, mixers, and phase shifters optimized for radar, electronic warfare, satellite communications, and test instrumentation. Their technical differentiation lies in precision microwave engineering, low-noise design, and thermal management for harsh environmental conditions, with a focus on meeting stringent MIL-STD and aerospace reliability standards. The firm’s engineering team applies advanced simulation tools and prototyping techniques to rapidly transition concepts into qualified hardware for mission-critical systems. Award history is not available to identify specific agency relationships or programmatic focus areas. Consequently, no definitive patterns can be established regarding which federal entities rely on their products or the nature of their engagements. The company operates primarily within the microwave and RF subsystem manufacturing sector, aligned with NAICS 334515, which encompasses the production of communication equipment and radar systems. Their market positioning centers on niche, high-reliability components for defense, space, and scientific instrumentation markets, where performance under extreme conditions is paramount. They serve as a specialized supplier to integrators requiring certified RF hardware with tight tolerances and repeatable performance. Polyphase Microwave Inc. is a small business entity structured as ZZ, headquartered in Bloomington, Indiana. The company holds no active government certifications such as 8(a), HUBZone, or SDVOSB. Its geographic footprint is limited to its Indiana facility, where all design, assembly, and testing activities occur. The firm maintains a focused presence in the federal defense electronics supply chain, emphasizing technical precision over scale.
