DIPLEXERS, TRIPLEXERS & MULTIPLEXERS


Lowpass, Highpass and Bandpass filters can be combined to form our state-of-the-art Diplexers/Duplexers, Triplexers and Multiplexers. API utilizes Suspended Substrate, Lumped Element and Cavity filters in our Multiplexer (MUX) designs.

Versatility is a hallmark that separates API Technologies from other filter companies. Choosing from a wide assortment of topologies, our engineers match the optimum topology for peak performance including iris coupling to reduce unit size and silver plating for lower loss.

We can provide RX/TX waveguide diplexers/duplexers in custom configurations.
