Abstract
A self-calibrating transceiver includes a transmitter chain, a receiver chain, a base band processor, and a calibration control state machine. The state machine is in electrical communication with the transmitter chain, the receiver chain, and the base band processor, and is configured for enabling the receiver chain and setting the receiver chain and the transmitter chain to corresponding frequencies. The state machine stores one or more transmitter power and power amplifier gain mode settings, and for each setting, sets the transmitter gain and power amplifier gain mode. The transmitter chain transmits a signal, the receiver chain receives the transmitted signal, and the baseband processor measures a received signal strength indicator (RSSI) of the received signal. The state machine further adjusts the transmitter output power based on the measured RSSI.
