Experiment Evaluation of a Multiport Harmonic Gunn Oscillator With Fundamental Signal Suppression

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, a multiport harmonic Gunn oscillator for oscillator arrays is proposed. The proposed oscillator consists of Gunn diodes, a slot-ring resonator and microstrip lines. The circuit has two ports. One of the ports is an output port for the second harmonic frequency and the other is a synchronization port for the fundamental frequency. The second harmonic output port has a band elimination filter to suppress the undesired fundamental signal. The oscillator is expected to be robust against its load fluctuation due to the filter. In this study, the proposed oscillator is experimentally evaluated. The oscillation frequencies were 10.1 GHz and 20.2 GHz at the fundamental and the second harmonic frequencies, respectively. The output powers at the second harmonic port were -6.0 dBm at the second harmonic frequency and -22.0 dBm at the fundamental frequency. The output powers at the fundamental port is 9.9 dBm at the fundamental frequency and -13.0 dBm at the second harmonic frequency. Undesired signals are suppressed at each port.
