Special RF Filters for Avionics

For Altimeters and Aircraft

Our design approach starts from your priorities - insertion loss, rejection and form factor

Let us help you solve your 5G interference problems

APITech designs and manufactures high-performance cavity filter solutions that allow 5G- C-band to take flight. 

The RF filter experts

The RF spectrum is becoming increasingly congested, which means filters are even more critical in providing effective fencing against crossover interference. RF filters are positioned to fuel the evolution of 5G technology as industries deal with 5G C-band and radio altimeter frequencies. We are the world's largest RF filter manufacturer and have been designing and building customized RF filter solutions for more than 50 years.

Custom-interface design

Our customers can weigh the benefits of size vs. loss, rejection vs. size, selectivity vs. group delay to select the perfect filter for system performance and value. 

Small, lightweight, rugged enclosure

Connectorized or surface mount, APITech can design custom packages that are easily multiplexed in designs that optimize footprint.

Versatile filter topologies

APITech designers are experts in the application of multiple topologies and, when needed, a mixture of topologies in a single unit. We offer a wide-range of custom or standard filter designs for military and commercial applications.
