rfic.eecs.berkeley.eduImage Reject Filter In our example, RF = 1000MHz, and IF = 1MHz.The Imagine is on 2IF = 2MHz away. Let’s design a filter with f0 = 1000MHz and f1 = 1001MHz. A fifth-order Chebyshev filter with 0.2dB ripple is down about 80dB at the IF frequency. But the Q for such a filter is Q = 103MHz 1MHz = 103 Such a filter requires components with Q > 103! A. M.
