Abstract

PURPOSE: To prevent the deterioration of characteristics caused by the higher harmonic component by inserting the higher harmonic elimination circuit to the loop circuit including the amplifier and thus reducing the undesired wave mode.
CONSTITUTION: The oscillation loop consists of amplifier 4, filter 7 and branching circuit 8 each. Amplifier 4 also amplifies the component of output frequency f2. Higher harmonic elimination circuit 9 eliminates the higher harmonic component generated due to the nonlinear characteristics of amplifier 4 or frequency converter 2 before return to amplifier 4 or circuit 2. As a result, such characteristic deterioration can be avoided as the occurrence of the uneven amplitude-frequency characteristics. And with application of the signal featuring frequency f1 to signal input terminal 1, the component of output frequency f2 is obtained at frequency converter 2 via oscillation frequencies f3 and f1. Here output filter 5 eliminates the component of frequency f2, and filter 7 extracts the component of frequency f3 each.
