CPI Diplexer 110045-23

CPI 110045-23 Ku-Band 4-Port Diplexer | 10.7–11.75 / 12.75–14.5 GHz

The CPI 110045-01 is a high-isolation Ku-band 4-port diplexer engineered for linear polarized satellite systems. It supports simultaneous Rx/Tx with outstanding rejection—115 dB Tx/Rx and 70 dB Rx/Tx—across 10.7–11.75 GHz (Rx) and 12.75–14.5 GHz (Tx). With 6 kW CW power handling (3 kW per Tx port), low insertion loss, and robust VSWR, this diplexer is built for high-power, high-performance SATCOM operations.
