Title:
2倍波発振器
Document Type and Number:
Japanese Patent JP5127362
Kind Code:
B2
Abstract:
A second harmonic oscillator has a series positive feedback configuration, suppresses output of a fundamental signal, and outputs a second harmonic signal having a frequency in a range from 1 GHz to 200 GHz generated inside of a circuit. The second harmonic oscillator includes: a transistor having a base terminal, a first emitter terminal, a second emitter terminal, and a collector terminal; a resonator circuit connected to the base terminal; a first transmission line shod-circuiting stub connected to one of the two emitter terminals; and a second transmission line short-circuiting stub connected to the other of the two emitter terminals and having a line length obtained by adding one-fourth of one wavelength of the fundamental signal to an integer multiple of one-half wavelength of the fundamental signal.
