Abstract
This paper present analysis, design and simulation of a compact VHF high power tubular band pass filter terminated with capacitor. In this analysis all effects of critical distributed and lumped structures are considered. Full wave simulator (HFSS) is used to analyze and optimize the filter performance and high power analysis done to achieve high power handling. The peak power in this filter considered above 10 kW and average power of about 1200 Watt. The insertion loss of VHF BPF filter is less than 0.6 dB and 0.2 dB bandwidth is about 10 MHz at the center frequency of 220 MHz, the stop-band attenuation is more than 30 dB at 205 MHz and 235 MHz (shape factor is 30 dB/Oct), return loss is better than 20 dB and so VSWR better than 1.2 in whole pass band. Moreover, the filter is compact in size and the dimensions are 4.5 cm × 50 cm.
