Abstract
A circuit with co-matching topology for transmitting and receiving RF signals for return loss improvement, wherein when transmitting RF signals, the LNA is turned off and the capacitance of an adjustable capacitive component is adjusted for transmitting RF signals, and when receiving RF signals, the power amplifier and the adjustable capacitive component are turned off, wherein a matching network is designed in favor of the LNA for receiving RF signals while the adjustable capacitive component can adjust the overall impedance of the circuit including the matching network that is also used when transmitting RF signals and the adjustable capacitive component for improving the transmitting return loss.
