We present the design and development of a compact, dual-band, wide stop-band band-pass filter on a multilayer organic substrate. The filter is designed based on quasi-lumped hybrid LC resonators that are coupled by shunt-inductor impedance inverters. The experimental results show that the filter has two passbands at 1.7 and 4.0 GHz with an out-of-band rejection level better than 50 dB up to 16.5 GHz.
