ADX MINI - MI2 LPF Bare PCB

ADX MI2 Low Pass Filter Bare PCB

The ADX MI2 Low Pass Filter PCB is designed for use in RF and SDR systems to effectively suppress unwanted harmonic frequencies and improve overall signal purity. Each filter is optimized for a specific frequency band, ensuring clean transmission and reception performance in multi-band radio applications.

This is a bare PCB kit, intended for custom assembly. It requires user-supplied components, allowing flexibility for builders who prefer to select their own parts or match specific RF performance requirements.

For best performance, the design specifies 0805 capacitors rated at 100V XR7 dielectric, ensuring stability and low loss at RF frequencies. Inductors are constructed using 26AWG enamelled copper wire, wound according to the included winding sheet and instructions.

Each board is supplied with detailed documentation to guide correct assembly, including coil winding specifications and component placement guidance.
