Abstract:
1. A high frequency oscillator which obtains an oscillation output by combining outputs of two oscillators, the high frequency oscillator comprising: a substrate; first and second amplifiers for oscillation so disposed on a first principal surface of said substrate that their output ends be opposite each other; a first signal line disposed on said first principal surface and configuring a closed oscillation loop by interconnecting an input end and the output end of said first amplifier; a second signal line disposed on said first principal surface and configuring a closed oscillation loop by interconnecting an input end and the output end of said second amplifier; and a grounding conductor disposed on a second principal surface of said substrate and configuring a strip line together with each of said signal lines, wherein an opening, where said grounding conductor is removed, is bored in said second principal surface and a coplanar line structure is configured by arranging said first and second signal lines close to each other in an area of said opening.
