The WEA50175LPF18CH322G is a leapfrog low pass filter with programmable cut-off frequency. The filter response is 3rd order Chebyschev. The low pass filter cutoff frequency can be selected from 40 MHz to 175 MHz. The resistors and the capacitors are programmable (6-bit and 4-bit respectively) and can be calibrated to minimize the low pass cutoff frequency accuracy due to process variation.
