Abstract:
1. A multimode millimeter-wave frequency divider circuit, which comprises: a signal input interface having at least a first input port, a second input port, a third input port, and a tuning voltage input port; a signal output interface having at least a pair of differential signal output ports, including a positive differential signal output port and a negative differential signal output port; and a frequency-dividing processing module, which in the case of an input signal appearing at the first input port is capable of performing a divide-by-2 frequency-dividing operation on the input signal; in the case of an input signal appearing at the second input port, is capable of performing a divide-by-3 frequency-dividing operation on the input signal; and in the case of an input signal appearing at the third input port is capable of performing a divide-by-4 frequency-dividing operation on the input signal; and which is further capable of outputting the frequency-downconverted signal through the signal output interface.
