The application of duplexers


Duplexers are widely applied in the field of communications, electronic warfare, it makes a certain interval of two frequencies to obtain larger isolation, can be roughly divided into three kinds: according to the use - duplexer, closed - accept duplexer, hair - hair duplexer.Received - sent duplex is used to prevent the launch large signal directly into the receiver front-end receiving channel saturation even burned, at the same time avoid the transmitter noise influence on receiving sensitivity;- accept duplex is used to share a pair of two different frequency of the receiver antenna, avoid direct use of the machine noise brought by the divider coefficient increases, and has function of primary signals;Hair - hair duplex is used in two different frequency of the transmitter share a pair of antenna, avoid using power loss brought by the combiner, and prevent the high-power transmitter influence each other, at the same time also can restrain harmonic output signal noise.The application of duplexers
