This is a surface mount (SMT or SMD) PCB for a Band Pass Filter (BPF). I will add components to target the 137MHz region so I can get better reception from the NOAA weather satellites. You can use whichever components you like for the frequency and bandwidth you want.
- SMA edge mount connectors x2
- 6pF 0603 cap: C3
- 13pF 0603 caps: C1, 2, 4, and 5
- 43nH 0603 inductors: L1 and L2
NOTE: Make sure that the caps and inductors have a self-resonant frequency (SRF) well above the frequency band you want (preferably at least 10x higher). Some component datasheets do not list this: DO NOT USE THESE FOR >1MHz!!!
