A duplexer is a component in radio devices operating in frequency division duplex (FDD) mode, used for sharing antennas.
This device plays a crucial role in preventing transmission waves from interfering with reception in radios that transmit and receive signals simultaneously. It is also referred to as an antenna duplexer or a diplexer.
There are two primary types of duplexers: bandpass filter type and bandstop filter type. The bandpass filter type allows the transmission wave's frequency to pass while blocking the received wave's frequency. These are generally compact and cost-effective. Conversely, the bandstop filter type permits the received wave's frequency to pass while blocking the transmission wave's frequency, providing superior performance in blocking transmission waves compared to the bandpass filter type.
