N2PK Vector Network Analyzer

An affordable 0.05...50MHz home made VNA of a Lab quality from Paul Kiciak, N2PK

This page is about my implementation of the N2PK Vector Network Analyzer (VNA), which is a lab quality instrument designed by Paul Kiciak, N2PK. If you have not heard about it, I recommend you read the set of comprehensive materials nicely documented and categorized, which could be found on Paul's WEB site. From there you can follow other links to get even more information. If then you decide you want to build it, you are welcome to come back here, where I will be posting information about my experience with the VNA.
