摘要: A new bandpass filter that is composed of two-stage microstrip-ring resonators with a center frequency 5.775 GHz and bandwidth 100 MHz presented in this paper. For the suppression unnecessary harmonics, low-pass filters are integrated into resonator. harmonic ratio about 35 dB for structure obtained. Also, varactor-tuned suggested, an insertion loss 6 tuning 450 obtained. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 26–29, 2001.
