DIY 1GHz Active Probe For Under 20$

DIY 1GHz Active Probe For Under 20$

thirschbuechler @ instructables.com shows us how to build a 1GHz active probe using BF998 dual-gate MOSFET and some other RF components.

This Instructable will show you how to build a 1GHz* Fet-based Active Probe, the Fetprobe, for about 10$*, provided you have access to an electronics lab. It is based on an Elektor-magazine article (see the pdf’s addendum, section literature in my thesis) beside some other designs. However, as topic of my bachelor-thesis I wanted to find out how good these designs really are and how far one can push them.
