9. A wireless communication system comprising at least one transceiver that communicates in a Time Division Duplex (TDD) scheme, the at least one transceiver comprising:
-
a first amplifier for amplifying an outgoing signal via an antenna during a transmission period; a second amplifier for amplifying a received signal received by the antenna during a receive period; a duplexer for coupling an output of the first amplifier to the antenna and coupling an input of the second amplifier to the antenna; a controller for generating a control signal to activate one of the first and second amplifiers while substantially simultaneously deactivating the other of the first and second amplifiers. - View Dependent Claims (10, 11, 12)

13. For use in a wireless communication system comprising at least one transceiver that communicates in a Time Division Duplex (TDD) scheme, a method of operating the transceiver comprising the steps of:
-
during a transmission period, amplifying in a first amplifier an outgoing signal for transmission via an antenna; during a receive period, amplifying in a second amplifier a received signal received by the antenna; generating control signals that selectively activate one of the first and second amplifiers while substantially simultaneously deactivating the other of the first and second amplifiers. - View Dependent Claims (14, 15, 16)
