Abstract
The authors report a maximally flat 10.7-MHz fourth-order bandpass filter with 68 dB dynamic range. The bandwidth and ripple of the filter are 250 kHz and 0.5 dB, respectively. The third intermodulation distortion is below -40 dB for fully differential input signals up to 3.4 V peak-to-peak. The supply voltages are +or-2.5 V. The filter architecture is based on two biquadratic sections in cascade.<>
