CPI Diplexer 114480-1

CPI 114480-1 Ka-Band 4-Port Diplexer | 19.2–21.2 / 29.0–31.0 GHz | CP

The CPI 114480-1 is a high-isolation, 4-port Ka-band diplexer designed for circular polarized transmit and receive applications. With ultra-low insertion loss (0.45–0.5 dB Rx, 0.4 dB Tx), excellent isolation (≥85 dB), and tight axial ratio control, it ensures optimal RF performance for high-throughput SATCOM systems. The unit supports 500 W per Tx port and is sealed to 5.0 PSIG for pressurized environments.
