CPI Diplexer 110025-11

CPI 110025-11 C-Band Diplexer | 60 dB Isolation, 500 W, Sealed

The CPI Model 110025-11 is a compact, pressurized C-band diplexer engineered for satellite ground terminals operating over 3.625–4.2 GHz (Rx) and 5.85–6.425 GHz (Tx). With symmetrical 60 dB isolation and low insertion loss, it supports full-duplex operation with minimized cross-talk. Its axial ratio ensures solid circular polarization support, and its 500 W CW rating makes it ideal for smaller SATCOM hubs or portable systems.
