Abstract:
A transceiver control circuit of a transceiver is disclosed including: a receiver circuit; a transmitter circuit; a shared filtering circuit shared by the receiver circuit and the transmitter circuit; a first mode-switch for switching signal input paths of the shared filtering circuit; a second mode-switch for switching signal output paths of the shared filtering circuit; a mode-switch control circuit for controlling the first mode-switch and the second mode-switch; a short-circuit switch coupled between two output terminals of a filter within the shared filtering circuit; and a short-circuit switch control circuit. In a period during which the transceiver transits from a receiving mode to a transmitting mode, the short-circuit switch control circuit turns on the short-circuit switch for a certain period and then turns off the short-circuit switch.
