What Microwave Products Group does

Microwave Products Group (MPG) is a wholly-owned operating segment of Dover Corporation that designs and manufactures mission-critical RF and microwave engineered electronic components and subsystems. The group unifies seven legacy brands—K&L Microwave (est. 1971), Dow-Key Microwave (est. 1945), Pole/Zero (est. 1991), BSC Filters (est. 1989), Espy (acquired 2021), Criteria Labs (acquired 2024), and the MPG Solutions platform (launched 2022)—under a single organization serving aerospace, defense, communications, space, GPS, and automated test equipment markets. Primary end customers include NASA, the U.S. Department of Defense, the U.S. Air Force, Boeing, and allied governments, with MPG products featured in over 150 space programs and aboard platforms such as the James Webb Space Telescope, GPS III, and the P-8A Poseidon.

MPG's product portfolio spans four core lines: filters (bandpass, bandreject, highpass, lowpass, multiplexers, cavity, waveguide, suspended substrate, thin film, and tunable) sourced across BSC Filters, K&L Microwave, and Pole/Zero; electromechanical RF switches (coaxial, waveguide, high power, high repeatability, and space-qualified) sourced primarily from Dow-Key, which the company identifies as the world's largest manufacturer of electromechanical RF switches; integrated subsystems and solutions under MPG Solutions, including cosite interference mitigation equipment (ICE), frequency converters, switch matrices, switched filter banks, and low noise amplifiers; and spectrum operations products from Espy, including teamSENTINEL wideband RF signal search/discovery, teamSOIGNE precision geolocation, and RFML (Radio Frequency Machine Learning) capabilities for automated signal classification. The group operates manufacturing and engineering facilities in the United States (Austin, TX; Salisbury, MD; Ventura, CA; Cincinnati, OH) and the United Kingdom (York), with over 182,000 square feet of technical workspace, AS9100D and ISO 9001:2015 certifications, and NASA/ESA space product approvals.

MPG sells primarily through direct enterprise sales supported by an RFQ-based quoting system and a global representative firm network, with engineer-to-engineer engagement as a core differentiator. Pricing is custom and quote-based against multi-year defense and aerospace contracts, with revenue driven by program awards (e.g., $66M and $53M P-8A Poseidon contracts), large-scale platform deployments, and replacement/service contracts. The customer base is concentrated in government and prime defense contractors, which provides long-cycle revenue visibility but also creates exposure to government budget cycles and program timing. MPG's expansion trajectory has been driven by acquisitions (most recently Criteria Labs in August 2024) and product launches (three RFML products at AOC Europe 2026), reflecting a strategic shift from discrete components into integrated subsystems and AI-enabled signal intelligence offerings.
