Duplexers & Repeaters: Simultaneous Transmit-Receive Systems

Duplexers provide critical frequency domain isolation between transmitter and receiver paths in repeater systems, typically achieving 80-100 dB of isolation. These passive filter networks enable full-duplex operation on a single antenna through precise cavity resonator design and coupling mechanisms optimized for specific frequency splits.
