ABSTRACT:
A high frequency oscillator comprises a transmission line resonator having a midpoint which serves as a null potential point, a pair of active devices for oscillation respectively connected to a pair of mutually opposite-phase resonance wave points for the transmission line resonator, and a plurality of output lines each having one end connected to the transmission line resonator at a point symmetric to the midpoint, and the other end commonly connected to a connection. The pair of active devices share the resonator and oscillate in opposite phases to each other. The plurality of output lines are coupled to the transmission line resonator respectively at maximum displacement distribution points for a standing wave of an 2n-th harmonic in the transmission line resonator, where n is an integer equal to or larger than two. Even-order harmonic components of 2(n−1)-th or lower are suppressed at the connection.
