Abstract :
A multi-resolution channel select filter topology is proposed for ultra-wideband coverage, as the multi-stage cascade of bimodal filters with self-complementary periodic frequency response. A 4-stage implantation based on PIN diode switches is presented. This prototype covers DC-2.5 GHz in 16 equal bandwidth channels of 156 MHz with a maximum insertion loss of 6.5 dB.
