Microwave Filter Company, Inc. (MFC) is a leader in the design, development and manufacture of high quality filter products since 1967.

The facility is equipped with an impressive complement of analytical and design software, test instrumentation, prototype and manufacturing equipment to create passive filters, components and subsystems.

The Manufacturing Facility Includes:

  • State-of-the-Art CAD-CAM system
  • A test department with automated network analyzers to 50 GHz
  • A high capacity conveyor soldering oven
  • A coating/finishing operation
  • A fully compliant TQM/ISO9000 based quality assurance program to insure the intrinsic quality of the products produced

All MFC filters are produced within our modern 40,000 square foot facility by a staff that is "Committed to Excellence".

MFC Also Offers:

  • Interference Filters for C- Band installations, including 5G, Satellite & Wireless.
  • Our Team has been involved in a number of programs serving:
  • Communications
  • Broadcast and CATV operators and installers
  • Military/Aerospace facilities
  • Universities and Government research labs
  • Wireless cable multi- channel, multi-point manufacturers, and Distribution Systems
  • C-band and Ku-band satellite Systems
  • A Complete Line of CATV headend channel deletion filters and networks, bandpass filters and diplexers for wireless and PCS applications.

MFC can offer an immediate opportunity to mitigate tariff-driven disruption to your mission with secure, U.S.-based sourcing for high-performance filters and microwave components.
Microwave Filter Company (MFC), based in East Syracuse, NY, has over 57 years of experience designing and manufacturing cavity, coaxial, and waveguide filters used in defense, aerospace, and satellite communications. Our filters have flown on aircraft like the F-16 and supported U.S. SATCOM platforms—and we are positioned right now to support YOU with localized, ITAR-compliant, tariff-immune capacity.

Why This Matters Right Now:
Current Tariffs and the threat of further tariffs on Chinese electronics are driving global shortages and pricing volatility for key RF components—including those widely used in satellite ground infrastructure.
Signal performance, especially in C, L, and Ka bands, depends on clean, interference-resistant filtering—and the window to secure domestic sources before deployment is closing.
We are a U.S. factory with in-place engineering, machining, tuning, and test capacity ready to support:

  • Filter qualification and custom tuning for your band plan
  • Rapid evaluation unit delivery (<3 weeks for most formats)
  • Integration into LNB/filter assemblies or vendor-qualified RF modules

Options to Consider:

  • Directly Qualify MFC Filters: Accelerate qualification for cavity and waveguide filters for your uplink/downlink chains. We’ll provide matched performance specs and fast prototypes.
  • Use MFC as a Regional Backup: Even if your primary suppliers are overseas, MFC can serve as an immediate overflow or risk mitigation partner.
  • Collaborate with Global Vendors: If you continue working with international RF vendors, MFC can provide local U.S. machining and tuning capacity under NDA to accelerate deployment and ensure tariff resilience.

Next Steps:
We’d welcome a 20-minute conversation to review your RF filtering roadmap, share our product catalog and spec sheets, and define where we can step in today—at no cost or commitment—to support your speed and resilience goals.

Warm regards,
Carl Fahrenkrug Jr.
President, Microwave Filter Company
