RF Solutions

Waveguide Filters

Waveguide bandpass filters consist of half wavelength resonant cavities couple by capacitive or inductive irises.  These high Q structures provide low passband loss and steep attenuation skirts.

SAW Filters

API provides high performance SAW filters to meet today’s military and commercial requirements.  The SAW filters range in frequencies from 20 MHz to 2600 MHz and offer a wide array of features.

Suspended Substrate Filters

API engineers combine both lumped and distributed elements onto one suspended substrate board, providing enhanced unloaded Q and exceptionally low insertion loss in one design.

Ceramic Filters

API follows strict ISO9001:2000 guidelines when manufacturing Ceramic Filters, ensuring affordability and top notch quality.  The Company’s unique design also integrates Low Pass Filters for Ultimate Rejection Optimization.

Tubular Filters

API’s line of tubular filters provide high unloaded Q’s in a moderate package size.  Due to their mechanical configuration, tubular filters have inherently broad stopbands with very high attenuation levels.

Cavity Filters

Cavity Filters designed and manufactured by API are high Q structures for high selectivity, with low passband insertion loss, important for receiver front end or high power transmit applications.

Lumped Elements

Lumped Element filters consist of discrete capacitors and inductors soldered to a substrate in various schematic configurations.  These compact designs are particularly suitable for applications where size is critical.

Switched Filter Banks

API draws from a team of specialists in amplifiers, filter, thin film, mixers, and switches to deliver a unique switched filter bank design that offers increased longevity, meets specifications, and exceeds expectations.

Diplexer, Triplexer, and Multiplexer

API desgins Diplexers Triplexers & Multiplexers through the use of modern techniques including a wide range of topologies, novel packaging, and innovative designs.

Band Reject Filters

API’s reputation for designing and delivering some of today’s most challenging Band Reject Filters is the reason why RF engineers trust us with their designs.
