Abstract
Radio frequency front-end matching circuits suitable for a transceiver module with TR switch integrated in a transceiver chip. The radio frequency front-end transceiver module comprises a radio frequency (RF) front-end device, a transmit/receive (TR) switch, a transmitter, a receiver and an internal matching circuit, in which the TR switch, the receiver, the transmitter and the matching circuit are integrated in one chip. The internal matching circuit is disposed at the first signal transmission path or the second signal transmission path selectively. The internal matching circuit is connected between the TR switch and the receiver when disposed at the first signal transmission path (receiving path) or between the TR switch and the transmitter when disposed at the second signal transmission path (transmitting path), such that the RF front-end device is impedance matched to both the receiver and the transmitter.
