Waveguide duplexer with ceramic filter technology rivals air-cavity devices

CTS Corporation (Elkhart, IN) through its subsidiary, CTS Electronic Components, Inc., announces its new ClearPlex Waveguide Duplexer, delivering performance comparable to air-cavity with 2x to 4x smaller size, according to the company, for cellular infrastructure, 6-10 GHz microwave, NLOS backhaul and military communications. The ClearPlex uses patent-pending structures and proprietary ceramic formulations in duplexer and band pass filter configurations for 3GPP bands 1, 2, 4 and 7, with more bands in development. This technology can support input powers of up to 500 W peak and 50 W average. Key attributes include:

  • Low insertion loss of 1 to 2 dB.
  • Frequency ranges from 1700 MHz to 10 GHz.
  • Sharp rejection points reaching up to -80 dB.
  • Passive Intermodulation (PIM) levels less than -110 dBm
