Summarizing the above results, we get
x L1 =0.8x10.7mm,
x L12=2.3x21.2mm, gap=0.9mm
x L2=1x10.7mm
x L23=2.3x21.2mm
x Lo=2.3x5mm, for 50 ȟ
x Lp=1.6x8mm, for pin connection
The end of L1 and L2 are grounded.
Figure 16-10 shows the design of the entire filter. The simulation results are
shown in Figure 16-11.
