METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING HIGH FREQUENCY
First Claim
1. A high frequency transmitting and receiving apparatus of a wireless communication system, the high frequency transmitting and receiving apparatus comprising:
- a transmitting and receiving antenna;
a low noise amplifier that low-noise amplifies a signal that is received through the transmitting and receiving antenna in a reception mode;
a power amplifier that amplifies a signal to be transmitted in a transmission mode and that outputs the signal to the transmitting and receiving antenna; and
a switch that is connected between the transmitting and receiving antenna and the low noise amplifier and that is turned on in a reception mode and that is turned off in a transmission mode.

Abstract
A high frequency transmitting and receiving apparatus of a wireless communication system low-noise amplifies a signal that is received from a transmitting and receiving antenna through a low noise amplifier in a reception mode, and amplifies a signal be transmitted through a power amplifier in a transmission mode and transmits the signal through the transmitting and receiving antenna, and the high frequency transmitting and receiving apparatus is connected between the transmitting and receiving antenna and the low noise amplifier and turns on a switch in a reception mode and turns off the switch in a transmission mode, thereby separating transmitting and receiving signals.
