Power reduction and linearizing techniques of transmitters

A transmitter, comprising:

• a digital to analog converter to convert a digital code of a communication signal to an analog communication signal;
• a low pass filter configured to filter the analog communication signal;
• a mixer coupled to the low pass filter, the mixer configured to mix the analog communication signal with a local oscillator signal to produce a mixed signal;
• a power amplifier driver coupled to the mixer, the power amplifier driver comprising a first input and a second input, the power amplifier driver configured to provide gain to the mixed signal and steer the mixed signal to a high-band transformer or a low band transformer;
• a first capacitor coupled to the mixer and the first input;
• a second capacitor coupled to the mixer and second input;
• and
• an inductor coupled to the mixer and the power amplifier driver, the capacitors and the inductor configured to create a resonant frequency to attenuate frequency components at a determined harmonic of the local oscillator signal.

An integrated circuit, comprising:

• a power amplifier driver to amplify a communication signal;
• a mixer coupled to the power amplifier driver, the mixer configured to mix an analog communication signal with a local oscillator signal to produce a mixed signal;
• and
• a resonant circuit coupled to the mixer and a differential input of the power amplifier driver, the resonant circuit to create a resonant frequency to attenuate frequency components at a determined harmonic of the local oscillator signal, the resonant circuit comprising:
• a first capacitor coupled to a first input of the differential input;
• and
• a second capacitor coupled to a second input of the differential input.
