CPI Diplexer 110240-6

CPI 110240-6 C-Band 3-Port Diplexer | Linear | 3.625–4.2 GHz Rx / 5.85–6.425 GHz Tx

The CPI 110240-6 is a rugged, linear-polarized 3-port C-band diplexer engineered for high-isolation transmit/receive separation in shared-feed SATCOM systems. Covering 3.625–4.2 GHz (Rx) and 5.85–6.425 GHz (Tx), it offers ≥70 dB port isolation, 1 kW CW power handling, and robust environmental protection with chromate and zinc-nickel finishes. Ideal for hub stations and gateway antennas using a common aperture for Tx/Rx paths.
