Abstract:
In an embodiment, a circuit device for coupling to an antenna includes a first impedance matching circuit configured to couple to the antenna and a second impedance matching circuit configured to couple to the antenna. The circuit device further includes a power amplifier coupled to the first impedance matching circuit and includes a low-noise amplifier coupled to the second impedance matching circuit. Additionally, the circuit device includes a selectable impedance adjustment circuit coupled between the low-noise amplifier and the second impedance matching circuit, which selectable impedance adjustment circuit is configured to selectively adjust an impedance associated with the low-noise amplifier when the power amplifier is transmitting a signal through the antenna.
