Abstract: An integrated circuit. The integrated circuit comprises an analog transmit chain, an analog receive chain, a processor coupled to the analog transmit and receive chains, and a non-transitory storage coupled to the processor and storing executable code. When executed by the processor, the executable code causes the processor to cause a portion of a radio frequency (RF) signal to be transmitted by the analog transmit chain, to determine a first direct current (DC) voltage of a baseband signal provided by the analog receive chain, to cause a DC voltage offset to be input into the analog transmit chain, to determine a second DC voltage of another baseband signal provided by the analog receive chain, to determine a DC voltage offset compensation based on the first and second DC voltages and the DC voltage offset, and to cause the DC voltage offset compensation to be used to transmit signals.
