Our program experience includes communication uplink systems, point to point (line of sight) communications, and virtually every wireless telecom protocol. API designs and manufactures filters in the 10 MHz – 50 GHz frequency range, with stop bands to 70 GHz. Whether your design is a bandpass, lowpass, highpass, bandreject, diplexer, triplexer, multiplexer, or multi-functional assembly, API continues be your top source for microwave components.

In order to optimize rejection and minimize loss, our expert engineers can utilize multiple topologies in a single small housing design. API’s broad filter capabilities support optimization of performance, size, and cost requirements. Our customers are able to weigh the benefits of size vs. loss, rejection vs. size, selectivity vs. group delay, and select the perfect filter to optimize system performance and value.

API offers rapid cell bandpass filters in the following topologies: surface mount ceramic covering 400 MHz – 2500 MHz, cavity with SMA connectors covering 800 MHz-20 GHz and lumped element covering 1 MHz – 3 GHz with the following options: SMA connectors, surface mount or PC Pin. Our rapid filter solutions are for moderately complex, standard design options, and can be delivered in as little as 2-4 weeks. API Technologies’ reputation for designing and delivering some of today’s most challenging RF & Microwave filters is the reason why RF engineers trust us with their designs.
