the theory and experiment of a new kind of millimeter wave quasi-optical power combiner
that is
compound quasi-optical power combiner are studied.It is shown that it has higher output power and combining efficiency because of the improved impedance-matching of diodes and increased jection-locking power.At 35.6GHz
the output power and combining efficiency of the quasi-optical power combiner including four Gunn diodes are 816mW and 96.3%
respectively.And the mechanical tuning range(≥100mW output)is about 860MHz.
