Duplexers enable the transmission and reception of signals on the same frequency without them interfering with each other. This is done by isolating the transmitter from the receiver while still allowing them to share a common antenna. As such, duplexers are of critical importance to many means of two-way communication, including radios, mobile phones and base stations.

Our selection of duplexers comes with options for DL/UL passband and stopband range, attenuation, max. insertion loss, power and size. In addtion, our products feature a universal PCB footprint for easy board population.
