DIY Vector Network Analyzer

What to do when a piece of test equipment is too expensive?  Henrik Forstén decided to design and build his own:

Cheap homemade 30 MHz – 6 GHz vector network analyzer

Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits

Since I can’t afford even a used VNA I decided to make one myself with a budget of 200€, tenth of what they cost used and about 1/100 of what they cost new

The design files and source code are available on GitHub:
