Filter Techniques

Our core competence

Cirocomm's dielectric resonator filters feature high outband rejection, low insertion loss, high power input and excellent temperature coefficient, which are mainly used for WiFi 5GHz, WiFi 2.4GHz, LTE small cell, DSRC and GPS applications. We shrink the DR filter size by use of ceramic and high K value materials.
