When you building QRP-Labs LPF or BPF filters, you may want this simple and easy to use adapter to test them with your NanoVNA, VNA or SpectrumAnalyzer with TG to get the best performance out of your filters.
I had a few QRP-labs lowpass filters and bandpass filters kits laying around and because I had nothing better to do on a afternoon, I fired up the soldering station and assembled them. After that they need to be tested and tuned and owning a NanoVNA for a few months I decided to use the NanoVNA for tuning the filters. After building a simple junkbox adapter, I found out that other hamradio operators like the idea and asked I could build one for them. So I designed a nice PCB, did some rework and came out on the current design.
The design allows you to simply calibrate your NanoVNA, VNA or spectrum analyzer and test / adjust QRP-labs lowpass filters and bandpass filters kits to your specification.
Note When using a NanoVNA, you can simple test components with this adapter. By directly insert the component under test into the Input socket (the top 2 sockets are ground, the bottom 2 sockets are connected to CH0 / S1). On Youtube there are some excelent video's about this topic (like this one)
Product is delivered as a kit with all components needed which requires soldering skill. But don't worry about the SMD parts, I have pre-soldered them for you.
Kit includes :
Note : Excluding the SMA coax cables, filter, large thumb crews, and the NanoVNA shown in the pictures.
