Duplexer
12 resonant cavities, isolation ≥ 85 dB
Product catalogue page 13
Transmit / receive path separation on a shared antenna line
What this unit does in the system
Allows bi-directional communication over a single path. The duplexer isolates the receiver from the transmitter while permitting transmit and receive to work at the same time. A design of high isolation and low insertion loss separates the TX/RX signal and avoids signal interaction. 12 resonant cavities satisfy a maximum 4 MHz band.
