Abstract:
1. A wireless communications device, comprising: a local oscillator comprising: a transmitter having a second mixer configured to mix the third signal and a fourth signal; and a receiver having a third mixer configured to mix the third signal and a fifth signal with a first control signal applied to the programmable divisor input, wherein the first oscillator comprises a voltage controlled oscillator, wherein the local oscillator comprises a phase locked loop configured to control the first frequency of the first signal generated by the voltage controlled oscillator, wherein the local oscillator comprises a second oscillator and a second frequency divider, wherein the second frequency divider is operatively coupled to the second oscillator, wherein the voltage controlled oscillator is phase locked to an output of the second frequency divider, wherein the second frequency divider comprises a programmable divisor input, wherein the third signal and the fourth signal are mixed by the second mixer with a second control signal applied to the programmable divisor input, and wherein the second control signal is different from the first control signal.
