Abstract: Wireless circuitry can have an antenna connected to a transmitting amplifier and a receiving amplifier. The wireless circuitry may be operable in a transmit mode during which only the transmitting amplifier is active and in a receive mode during which only the receiving amplifier is active. The transmitting amplifier may be connected to the antenna via a balun and a radio-frequency coupler without an intervening switch that is enabled during the transmit mode and disabled during the receive mode. The transmitting amplifier may include input transistors, cascode transistors, first switches configured to selectively decouple gate terminals of the cascode transistors from a bias voltage, output capacitors, and second switches configured to selectively decouple the output capacitors from a ground line. The first and second switches are turned on during the transmit mode and are turned off during the receive mode to increase an output impedance of the transmitting amplifier.

Abstract: This disclosure is directed to reducing output voltage distortions of Variable Gain Amplifiers (VGAs). A VGA may include a number of amplifiers each providing a portion of a total gain of the VGA. For example, a processing circuit may select one or more of the amplifiers of the VGA to provide the output signal with a selected gain. However, the selected amplifiers may provide amplified signals with one or more distortion signals when receiving a bias voltage. Systems and methods are described to reduce or cancel the distortion signals of the selected amplifiers by providing a subthreshold nonzero bias voltage (e.g., a weak voltage) to the remaining (e.g., non-selected) amplifiers of the VGA. For example, the non-selected amplifiers may receive the weak voltage to provide distortion signals with similar voltage amplitude and out of phase compared to the distortion signals of the selected amplifiers.
