Abstract:
A transmitter system comprising:a first phase locked loop for generating a first signal having an intermediate frequency, said first phase locked loop comprising a first frequency divider circuit having a first divider coefficient;a second phase locked loop for generating a second signal having a translation frequency, said second phase locked loop comprising a second frequency divider circuit having a second divider coefficient;a third phase locked loop connected to said first and second phase locked loops for generating a third signal having a transmit frequency, the value of the transmit frequency being equal to the sum of the values of the intermediate and translation frequencies, wherein the values of the intermediate and translation frequencies are programmable by said first and second divider circuits and said transmit frequency is incrementally varied by varying the first and second divider coefficients of the first and second frequency divider circuits in opposite directions.
