Transceiver and related switching method applied therein

摘要

A transceiver includes a power amplifying circuit, a first balance-unbalance circuit, a switchable matching circuit, and a low-noise amplifying circuit. The power amplifying circuit generates differential output signals during a transmitting mode of the transceiver. The first balance-unbalance circuit converts the differential output signals into a single-ended output signal. The switchable matching circuit receives the single-ended output signal on a signal port of the transceiver during the transmitting mode, and converts a single-ended receiving signal on the signal port into a single-ended input signal during a receiving mode of the transceiver. The low-noise amplifying circuit converts the single-ended input signal into a low-noise input signal during the receiving mode.

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.
