    摘要: A method and an apparatus for analyzing performance of a multi-stage radio frequency amplifier are described. The method simplifies the multi-stage radio frequency amplifier into equivalent input parts, output parts and mid-stage parts. The mid-stage parts are temporarily unset. Therefore, the equivalent input parts and output parts will be adjusted to make best gain performance and the mid-stage parts will be the next targets for analysis. Repeating the above-mentioned methods for decomposing the circuit can systemize the method for analyzing circuits and problems in each part of the circuit may be found more quickly.

    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.
