Abstract:
1. A method comprising: determining a saturated output power associated with a power amplifier of a communication network device, wherein the saturated output power is a maximum power level associated with the power amplifier, wherein the communication network device is configured to operate in accordance with a first operating parameter; providing a radio frequency (RF) signal at the saturated output power via a loopback path that couples a transmitter unit and a receiver unit of the communication network device; measuring a received power of the RF signal received via the loopback path; determining a first loopback gain associated with the communication network device based, at least in part, on the saturated output power and the received power of the RF signal received via the loopback path; calibrating an output transmit power of the power amplifier when the communication network device is configured to operate in accordance with the first operating parameter based, at least in part, on the first loopback gain associated with the communication network device; determining a second loopback gain associated with a second operating parameter when the communication network device is configured to operate in accordance with the second operating parameter; determining a gain difference between the first loopback gain associated with the first operating parameter and the second loopback gain associated with the second operating parameter; and calibrating the output transmit power of the power amplifier when the communication network device is configured to operate at the second operating parameter based, at least in part, on the gain difference and the calibrated output transmit power of the power amplifier when the communication network device is configured to operate at the first operating parameter.
