Hi, Just to continue the line of thought of loose-electron I've seen a type of filters called "Q-enhancement Bandpass Filters" that are proposed as integrated RF Bandpass filters, first time I've seen them was in a tutorial from ISCAS 2004:"Design of Continuous-Time Filters from 0.1Hz to 2.0GHz",Edgar Sanchez-Sinencio and Jose Silva-Martinez, surfing the web you could find some IEEE papers and I've found also a Thesis:"A Q-ENHANCED 3.6 GHZ TUNABLE CMOS BANDPASS FILTER FOR WIDEBAND WIRELESS APPLICATIONS",JIANDONG GE,University of Saskatchewan,Canada. I suppose that they could be used if power consumption and/or the trade off between NF and linearity are too stringent.
