Homebrewed SMD PLP/PHP filters for KE5FX link
---------------------------------------------
You can substitute the MCL filters used in the original design with homemade
ones, taking the values from the table below, or can design your owns. 

Chevyshev
LP20MHz     C1,4=180p    C2,3=330p    L1,3=583n    L2=650n
LP200MHz    C1,4=18p     C2,3=33p     L1,3=58.3n   L2=65n
HP100MHz    C1,4=47p     C2,3=18p     L1,3=61.8n   L2=51.5n

Bessel
LP20MHz  C1=18p  C2=82p  C3=120p  C4=330p  L1=120n  L2=270n  L2=430n

Low pass and high pass filters can be arranged as shown, using the same pcb
holes of the canned ones. Althought isn't difficult to built these filters
you probably will need to tune its coils to get a good shape.
