Dept. of Electrical Engineering, Indian Institute of Technology, New Delhi Computer aided design of inductive iris filter in waveguide technology is described here using Mode Matching Method(MMM). Direct coupled cavity niters form compact structures. Such a bandpass filter is first designed using equivalent network theory approach.(More)
A Class F power amplifier (PA) at 2.5GHz has been designed and fabricated. Test results show 15.7 dB gain with 75.75% power added efficiency (PAE ), at an input level of 25 dBm. The design procedure is presented, with various issues illustrated and addressed. A new method is proposed to obtain the optimum load and source impedances without iterations, which(More)
