TRANSCEIVER AND RELATED SWITCHING METHOD APPLIED THEREIN

摘要

A transceiver includes: a power amplifying circuit arranged to generate differential output signals during a transmitting mode of the transceiver; a balance-unbalance circuit arranged to convert the differential output signals into a single-ended output signal; a switchable matching circuit arranged to receive the single-ended output signal on a signal port of the transceiver during the transmitting mode, and to convert a single-ended receiving signal on the signal port into a single-ended input signal during a receiving mode of the transceiver; and a low-noise amplifying circuit arranged to convert the single-ended input signal into a low-noise input signal during the receiving mode. The power amplifying circuit, the Balun, the switchable matching circuit, and the low-noise amplifying circuit are configured as a single chip.

1. A transceiver, comprising:
a power amplifying circuit, arranged to generate differential output signals during a transmitting mode of the transceiver; a first balance-unbalance circuit (Balun), arranged to convert the differential output signals into a single-ended output signal; a switchable matching circuit, arranged to receive the single-ended output signal on a signal port of the transceiver during the transmitting mode, and to convert a single-ended receiving signal on the signal port into a single-ended input signal during a receiving mode of the transceiver; and a low-noise amplifying circuit, arranged to convert the single-ended input signal into a low-noise input signal during the receiving mode;wherein the power amplifying circuit, the first Balun, the switchable matching circuit, and the low-noise amplifying circuit are configured as a single chip.
