摘要
A signal at oscillator frequency (A) is supplied to the node (3). The mixer (4) has a first input (5), second input (6) and output (12). The first signal path (7) couples the oscillator frequency from the node to the mixer first input. The second signal path (8) includes a frequency divider (10) (flip-flops) connecting the node to the second mixer input.
