A transmitter includes a first variable gain amplifier (VGA) and a second VGA coupled to an output of the first VGA. The first and second VGAs each comprise a plurality of parallel gain stages. Gains of the first and second VGAs are equal to the sum of the gains of the activated parallel amplifiers within each corresponding plurality of parallel amplifiers. Each parallel amplifier comprises a parallel differential amplifier controlled by a pair of switches to activate and deactivate the parallel differential amplifier. The gains of the first and second VGAs are increased by activating additional parallel amplifiers. The gains of the first and second VGAs are decreased by deactivating additional parallel amplifiers. The variable gains of the first and second VGAs provide an extended gain control with improved local oscillator (LO) leakage interference rejection.
