Abstract: A wireless data transceiver comprises a voltage controlled oscillator configured to generate a first time-varying signal. The transceiver further comprises an antenna configured to receive a signal wirelessly over a network. The transceiver further comprises an amplifier configured to amplify the signal. The transceiver further comprises a frequency mixer coupled to the voltage controlled oscillator and the amplifier. The frequency mixer is configured to generate a second time-varying signal based on the first time-varying signal and the amplified signal. The transceiver further comprises a power detector configured to measure a characteristic of the second time-varying signal. The transceiver further comprises an automatic gain control circuit coupled to the power detector and the amplifier. The automatic gain control circuit is configured to adjust operation of the amplifier based on the measured characteristic, a minimum power setting, and a maximum power setting.
