ABSTRACT:
A transmitter system having an adjustable monolithic frequency stabilization and tuning internal capacitor circuit. The transmitter system has a transmitter for generating and transmitting a transmitter oscillator frequency signal. A data generating chip is coupled to the transmitter. The data generating chip is used for adjusting and controlling the transmitter oscillator frequency signal. A variable capacitor circuit is located internal to the data generating chip and is coupled to a ground pin and one of a plurality of function pins on the data generating chip. The variable capacitor circuit is used for adjusting and setting the centerpoint of the transmitter oscillator frequency signal.
