Abstract:
1. A semiconductor integrated circuit device comprising: a resonant circuit resonating at an arbitrary frequency; a transmission line for transmitting a high-frequency signal having the frequency, wherein a first end of said transmission line is connected to said resonant circuit; an active element having a first electrode connected to a second end of said transmission line, a second electrode which is grounded through a reactance element, and a third electrode; an output-matching circuit including a diode section for regulating an oscillation power and a high-frequency signal output terminal, wherein a first end of said diode section is connected to said third electrode of said active element, and said high-frequency signal output terminal is connected to a second end of said diode section; and a substrate having a main surface on which said resonant circuit, said transmission line, said active element, and said output-matching circuit are arranged.
