This subsystem is an agile filter/amplifier cascade for the UHF frequency band with a VHF bypass. It enables simultaneous operation of multiple transceivers in the co-site environment. The ICE3004 provides multiple poles of RF selectivity to reduce broadband noise, harmonics, and spurious signals while still providing full output power in transmit mode and excellent selectivity to interfering signals at the transceiver’s RF input in receive mode. All transmit, receive, and bypass switching is incorporated into the two-port design. This filter incorporates extensive Built-in-Test capability and is qualified for airborne applications. |
