Chebyshev BPF. PCB design #2.

After some short discussion (or rather asking questions) the design of the PCB has been changed. Now all coils are placed onto the line, capacitors are located symmetrically in respect to coils. The second view of the PCB is following.

Chebyshev BPF: designing the PCB.

Recently I realized I need some number of filters of a different kind: lowpass, highpass and bandpass. The ready-for-use ones are pretty expensive and cannot be customized for my needs. Therefore I have decided to start building my own ones.

Everything starts from scratch. In my case - the schematic. I have dug the Internet and found some number of diagrams I could use. Below is the one I have used for my work. This is a bandpass filter developed by Sinisa Tasic-Tasa, YU1LM. A very good starting point.
