Abstract:
The disclosure relates to transceivers incorporating a transmit-receive switching circuit, embodiments of which include a radio transceiver circuit comprising: a first amplifier for amplifying signals received from an antenna via an antenna connection; a second amplifier for amplifying signals to be transmitted by the antenna via the antenna connection; and a switching circuit connected between an input of the first amplifier and the antenna connection, the switching circuit comprising a capacitor, a switching element and an impedance matching element, wherein the switching element is configured to connect a node between the capacitor and the impedance matching element to a signal ground when the transceiver is in a transmit mode.
