摘要： A frequency synthesizing circuit comprising a first mixer configured to receive a first input signal at a first input thereof, a first filter configured to receive an output signal of the first mixer and remove undesired signal frequencies from the output signal of the first mixer, and a feedback loop. The feedback loop includes a second mixer having a first input connected to the output of the first filter and a second input for receiving a second input signal. The second mixer is configured to mix a signal received at the first input with the second input signal. The feedback loop further includes a third mixer having a first input connected to an output of the second mixer and a second input for receiving a third input signal. The third mixer is configured to mix a signal received at the first input with the third input signal.
