From the project
RF "Lego" blocks. Quite-Linear HF broadband RF amplifier experiments for higher bands.
The Finals-RD15.kicadpcb` is oversized on purpose for two reasons:
- To avoid the tedious job of cutting the larger 3x2 PCB into a smaller size.
- To save etchant by putting a copper pour over the larger area.
