A Study on the Realization of X-Band Harmonic Generator
X-밴드 고조파 발생기의 구현에 관한 연구
Abstract
In order to realize an efficient and stable X-band harmonic generator, a 100 MHz frequency multiplier, an impulse generator using SRD(Step Recovery Diode) module, and a narrow-band bandpass waveguide filter have been designed and tested. By properly combining these devices an X-band harmonic generator has been realized. The output power of the harmonic generator was measured to be -1.5 dBm at 9 GHz which is the 90th harmonic of the 100MHz input. The power fluctuation of the harmonic generator due to temperature variation was observed to the about 0.15 dB during 24 hours of 4\ulcorner temperature variation.
