    Abstract: Aspects include amplifiers with different units for improved performance. One amplifier has a first transistor with first gate is coupled to a control input, and a first drain is coupled to a first terminal of an output, a second transistor with a second gate is coupled to the control input, and a second drain is coupled to a second terminal of the output. The amplifier has a third transistor with a third drain coupled to the first transistor source, and a third gate is coupled to a first terminal of an input, and a fourth transistor with a fourth drain is coupled to the second transistor source, and a fourth source gate is coupled to a second terminal of the input, where the first transistor source is not connected to the second transistor drain via one or more transistors.

    Abstract: Aspects herein describe VSWR-tolerant operation of wireless communication devices. One aspect involves setting, using control circuitry of the wireless communication apparatus, a mission mode for an output transmission (Tx) power amplifier, measuring, using an output power detector, an output power of the output Tx power amplifier operating in the mission mode, measuring, using an input power detector, an input power to the output Tx power amplifier associated with the output power, sampling a thermistor signal to determine a junction temperature associated with the output power, calculating, using the control circuitry, a gain value for the output Tx power amplifier using the input power and the output power, comparing, using the control circuitry; the gain value with a temperature calibrated reference gain value selected using the junction temperature, and adjusting a power amplifier bias when the gain value is different from the temperature calibrated reference gain value.
