11. If the duplexer isolation is not sufficient then the handset may experience self-desensitization. 12. A blocking device ( a duplexer ), shut the receiver input when the transmitter pulsed. 13. The duplexer is a filter that provides isolation of the transmitter leakage to its own receiver. 14. Wilhelm Stepp developed a transmit-receive device ( a duplexer ) for allowing a common antenna. 15. Next up is a mechanical duplexer ( which a lot of office photocopier-type equipment has ). 16. In this example, consider a type of device called a " band-pass duplexer ". 17. In a mobile connected device, the transmitter and receiver are linked to the same antenna by means of a duplexer . 18. Other spark tubes had been used for this purpose, in a design known as the " Branch-Duplexer ". 19. To use a common antenna for both transmitting and receiving, Zahl invented a gas-discharge device, called a duplexer . 20. To prevent self-desensitization, a duplexer must attenuate Tx emissions at the own Rx frequency band below the Rx noise floor.
