ABSTRACT:
A multi-channel carrier wave generator includes a signal source capable of generating a carrier wave having a frequency, a first input-match diode circuit receiving the carrier wave to correspondingly generate a plurality of harmonic waves, a first multi-way power divider electrically connected to the first input-match diode circuit to equally divide the harmonic waves, and a first multi-way filter electrically connected to the first multiple power divider to filter through the harmonic waves. Such a multi-channel carrier wave generator has the advantages of having a simple fabrication procedure, a low cost, and a low phase noise, and capable of providing a stable carrier wave and a good filtering result and of using a lower order bandpass filter.
