Frequency-transformation-based co-designed lowpass-single/multi-passband-highpass RF filters

The theoretical design and practical development of RF analog filtering devices with co-integrated lowpass, single/multi-band bandpass, and highpass transfer functions is reported. For this purpose, two different classes of generalized frequency transformation that convert the equivalent normalized...
