The PhaseBlade is a flexible filter board for SDR and RF experimentation. Designed to support multiple build options, it lets you quickly assemble low-pass, high-pass, or band-pass filters using your choice of components.
Supports SMD, through-hole, or wound inductors
Works with standard capacitors for quick prototyping
Layout supports most basic 5-element filter topologies
Fits standard 1.6 mm PCBs with SMA edge connectors
Great companion for SDR frontends like the PhaseLoom
1 × PhaseBlade PCB (bare board only)
Components (inductors, capacitors)
SMA connectors or headers
Building custom filters for ham bands, shortwave, or SDR projects
Learning and experimenting with RF filter design
Quickly prototyping different filter types without ordering custom PCBs
✂ Cut the spectrum your way — the PhaseBlade makes filter building fast, simple, and fun.
The PhaseBlade gets its name and its explanation in this video — see the filtering section for what this board does to the signal, and why.
