The filter will reduce the emission of harmonics and increase the receiver selectivity. The filter topology is shown in Figure 44. Component values are given in Table 38. The filter is designed for 50 Ω terminations. The component values may have to be tuned to compensate for layout parasitics. The design equations for a 3dB equal ripple filter are: ⎟ ⎠ ⎞ ⎜ ⎝ ⎛ − ⋅ ⋅ ≈ 1333 . 0 1 1 2 RF C f π ω C L ω 6 . 35 = , C C ω 067 . 0 = where ω c is the cut-off frequency and fRF is the transmitted RF frequency.
