Cavity duplexer is a bidirectional three-terminal filter used in radio frequency communication transceiver circuits. It shares a transceiver system with an antenna to achieve signal isolation between the receiver and transmitter and ensure that the receiver and transmitter can work normally at the same time.
Features:
Small insertion loss, effectively reducing system power consumption; large power capacity, effectively increasing the number of system channels; high suppression, improving the system's anti-interference ability in microwave environments; small intermodulation products, improving reception sensitivity.
