Abstract:
1. A direct conversion Radio Frequency (RF) transceiver integrated circuit comprising: a local oscillator that generates a RF local oscillation signal corresponding to a RF channel; a receiver section operably coupled to the local oscillator that receives an incoming RF signal and down converts the incoming RF signal based upon the RF local oscillation signal to produce a baseband signal; a transmitter section operably coupled to the local oscillator that receives an outgoing baseband signal and up converts the outgoing baseband signal to produce an outgoing RF signal; and wherein the transmitter section further comprises: a heat generating circuit; a temperature sensor that produces a voltage without a common mode component as an indication of an operating temperature of the heat generating circuit; and at least one adjustable gain element operably having a gain setting that is based upon the indication of the operating temperature provided by the temperature sensor.
