Abstract :
Off-line tuning of leapfrog multiple loop feedback bandpass filters is demonstrated using a modification of Dishal´s method [1952]. The proposed method is suitable for high frequency, high Q bandpass filters, and has advantages including simplified tuning circuits and algorithms, minimal additional circuit parasitics and suitability for high frequency applications.
