摘要：
An RF front-end architecture is operated in either a transmitting or a receiving mode. The RF front-end architecture comprises an antenna, an impedance match network, a balun and a transceiver chip. The transceiver chip comprises first and second transmit/receive (TR) switches, a transmitter, and a receiver. Because two TR switches are integrated into the chip, the printed circuit board area, BOM cost and pin count of the transceiver chip can be greatly reduced.
