Antenna voltage standing wave ratio (vswr)-tolerant transmission power amplifier

A method of operating a wireless communication apparatus, comprising:

• setting, using control circuitry of the wireless communication apparatus, a mission mode for a Cascode sliced output transmission (Tx) power amplifier;
• measuring, using an output power detector, an output power of the Cascode sliced output Tx power amplifier operating in the mission mode;
• measuring, using an input power detector, an input power to the Cascode sliced 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 Cascode sliced 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 gain bit setting for the Cascode sliced output Tx power amplifier when the gain value has more than a threshold difference from the temperature calibrated reference gain value.

A method, comprising:

• setting, using control circuitry of a wireless communication apparatus, a mission mode for a multi-element output transmission (Tx) power path comprising a plurality of transmit elements;
• calculating individual gain values for the plurality of transmit elements;
• calculating a mean operating gain from the individual gain values;
• comparing the mean operating gain with the individual gain values;
• and
• adjusting a bias setting for one or more of the plurality of transmit elements when a first gain value of the individual gain values is not within a threshold distance of the mean operating gain.
