A wide tuning band pass filter (BPF) with steep roll-off high rejection and low noise figure is presented. The design feature of\nsteep roll-off high stopband rejection (>20 dB) and low noise figure (<6 dB) provides a wide tuning frequency span (1ââ?¬â??2.04GHz) to\naccept desirable signals and reject close interfering signals. The process variation aware design approach demonstrates robustness\nof the BPF after calibration from process variations, operating in 1.04GHz tuning frequency span: almost zero deviation on center\nfrequency, an average maximum deviation 1.16 dB on a nominal pass band gain of 55.6 dB, and an average maximum deviation\n1.06MHz on a nominal bandwidth of 12.3MHz.
