PhaseBlade Universal Filter PCB

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.

Features

• 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

What’s Included

• 1 × PhaseBlade PCB (bare board only)

What’s Not Included

• Components (inductors, capacitors)

• SMA connectors or headers

Perfect For

• 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.
