What Midwest Microwave Solutions does

Midwest Microwave Solutions (MMS) is a privately held designer and manufacturer of RF tuners, digitizers, digital signal processors, mmWave block converters, and RF upconverters/transmitters used in defense and intelligence signal-processing applications. Founded in May 2005 in Cedar Rapids, Iowa by Phil Rezin as an RF consulting and prototyping firm, the company co-developed its core tuner and digitizer product line with VP Steve Wilson before DSP expert Mike Horn joined as a partner in June 2009 and the business began independent operations. MMS relocated to a dedicated design facility in Hiawatha, Iowa in July 2010, situated adjacent to Rockwell Collins and other Cedar Rapids-area aerospace and defense engineering firms; in August 2015 HEICO Corporation acquired a controlling share and integrated MMS into its Electronic Technologies Group, giving the company access to a 19-facility, 275+ engineer aerospace and defense platform while retaining its operating identity.

The company's core technology centers on wideband, high-dynamic-range RF front ends tunable from 100 kHz to 70 GHz with embedded preselect filters and low-noise, fast-tuning synthesizers, paired with open-architecture digitizers featuring customer-flashable DSPs and FPGAs that deliver up to 80 MHz of digitized spectrum. Documented performance specifications include ultra-low phase jitter down to 0.1° rms and tune times under 500 microseconds, with phase-coherent tuning across multiple channels supporting electronic warfare and direction-finding applications. The product portfolio has expanded from the original tuner/digitizer base to include digital signal processors, mmWave block converters, and upconverters/transmitters, plus integrated rackmount subsystems and custom configurations, serving SIGINT, COMINT, ELINT, and software-defined radio use cases. MMS is an active member of the SOSA (Sensor Open Systems Architecture) Consortium, embedding its hardware into a DoD-mandated open-standards framework.

MMS generates revenue primarily through direct B2B enterprise sales of RF hardware (standalone units plus custom-integrated subsystems) to U.S. Government defense and intelligence programs and to defense contractors. Pricing is by quote through direct procurement processes, with no public price list disclosed. The company also provides Quick Reaction Capability (QRC) professional services to support evolving customer requirements and emerging threats. As of the most recent data, MMS employs 26 team members, including 14 engineers with over 200 years of combined experience drawn from heritage defense RF organizations including Watkins Johnson, Rockwell Collins, and Softronics Ltd. The company operates only in North America (United States), with all engineering and manufacturing conducted from its single Hiawatha, Iowa facility.

Direct peers

• Ultra Electronics (now part of Cobham): Ultra Electronics built RF tuners, digitizers, and SIGINT/COMINT subsystems for US and allied defense and intelligence programs — a near-direct historical comp to MMS in product scope and customer base. Now operating under a larger parent, but remains comparable on RF tuner/digitizer product category.
• National Instruments (NI): NI designs modular digitizers, SDR platforms, and FPGA-based RF acquisition hardware used in defense SIGINT, COMINT, and EW testbeds. Directly comparable open-architecture, FPGA/DSP-programmable digitizer technology serving defense SDR customers, now operating under Emerson's Test & Measurement group.
• Mercury Systems: Mercury Systems designs and manufactures mission-critical defense electronics, including RF/microwave components, embedded processing, and digitizers for EW, SIGINT, and C5ISR programs. Directly comparable to MMS in target customer (US DoD), product category (digitizers, RF subsystems), and SOSA-aligned open-architecture strategy, though at substantially larger scale.
• Keysight Technologies: Keysight manufactures RF/microwave test and measurement instrumentation including wideband digitizers, signal analyzers, and RF tuners for commercial, aerospace, and defense applications. Overlaps with MMS on digitizer and signal-acquisition technology, though Keysight is dominant in commercial T&M and broader in scale.
• Rohde & Schwarz: Rohde & Schwarz produces RF signal analyzers, digitizers, and communications-electronics receivers used in EW, COMINT, and SIGINT applications. Strongly comparable in RF tuner/digitizer product category and defense/intelligence customer base, though positioned as a global commercial T&M incumbent with broader portfolio.
• Kratos Defense & Security Solutions: Kratos operates a defense electronics business (including Kratos RF/EW products) building RF hardware and signal intelligence subsystems for DoD EW and radar programs. Directly comparable niche competitor in RF hardware for EW/SIGINT, though with broader unmanned-systems and microwave-product exposure.

Broad incumbents

• Curtiss-Wright Defense Solutions: Curtiss-Wright's defense electronics business provides rugged RF/microwave, signal processing, and COTS subsystems for US DoD platforms. Comparable in defense electronic subsystems for EW/sensor platforms, though positioned as a broader diversified defense supplier.
• Teledyne Technologies: Teledyne operates defense electronics, RF/microwave, and instrumentation businesses (Teledyne Defense, Teledyne Microwave Solutions) serving aerospace, defense, EW, and intelligence customers. Comparable in technical domain (RF/microwave and defense electronics) and customer base, though as a diversified conglomerate with many non-defense businesses.
• L3Harris Technologies: L3Harris is a prime defense contractor with major EW, SIGINT, and RF/microwave electronics franchises serving the US DoD and intelligence community. Overlaps with MMS in mission space (EW/SIGINT) and SIGINT-receiver technology, though at much larger prime-contractor scale spanning platforms, payloads, and integration.
• BAE Systems Electronic Systems: BAE Systems manufactures RF/EW systems, signal intelligence receivers, and digital RF subassemblies for US and allied defense customers. Comparable in RF/EW product domain and customer base, though operated as part of a global prime contractor with a much wider platform portfolio.
