| 摘要 |
This invention relates to a high-frequency oscillator constituted by a signal generator for generating a high-frequency signal and a signal output circuit for outputting the generated high-frequency signal. The signal output circuit comprises a capacitor having one terminal to which the high-frequency signal output from the signal generator is applied, and a microstrip line having one terminal, which is connected to the other terminal of the capacitor, and the other terminal set at a reference potential. This signal output circuit can be miniaturized compared with those constituted only by microstrip lines such as conventional signal output circuits. By properly setting the capacitance of the capacitor and the size of the microstrip line, a filter function can also be imparted to the circuit.
