Customized RF Components and Microwave

Both Diplexer and Duplexer can be translated as "duplexers", which are extremely common radio frequency components in transmitter circuits, receiver circuits, and transceiver circuits used in communications, radar, and other sensing applications. Diplexer and Duplexer are both three-port radio frequency devices; Duplexer is used to separate the transmit and receive paths according to the signal direction, and can be used for same-frequency signals, and Diplexer is used with filters to separates the signal by Frequency

Duplexer is a three-port radio frequency device whose purpose is to divide the antenna's transmit and receive signals into two different signal paths according to its direction. Among them, because the transceiver and receiver signals can have the same operating frequency band, Duplexer can truly realize two-way communication under the signal antenna.

Diplexer is also a three-port radio frequency device, which can use the frequency division function of high-pass, low-pass or band-pass filters, The same antenna or transmission line can be used for two signal paths so that the same antenna can receive and send two different frequency signals. In order for the Diplexer to work properly, the quality and attenuation of the filter used must be able to match the specifications of the two processing signals.
