Abstract
Provided is an apparatus for protecting a receiver circuit in a Time Division Duplexing (TDD) wireless communication system. In the protecting apparatus, an antenna switch transmits an output signal of a power amplifier to an antenna feed line and transmits an output signal of the antenna feed line to a low noise amplifier. A status monitor monitors a status of the antenna switch. A mode determiner disables an amplification operation of the power amplifier when a status monitoring signal output from the status monitor indicates an RX mode.
