RF BRIDGE 0.1 - 3000 MHz


To note please:

My original Bridges you can buy ONLY here in my web store or in my eBay store!

I am not supplying these Bridges to other sellers.

There are a lot of fake Bridges available on Ebay or in other online auctions. There is the fake product from China there! They even printed my web store URL on their fake Bridges.


With this known RF SWR Bridge board you can measure in thru-mode filters, amplifiers and in reflective mode antennas, impedances, inductance, capacitance and impedance matchings and much more.

Topography of PCB of this SWR Bridge was designed by David Fainitski and it was published in open source on his web site here

Last measurement showed that this RF Bridge works great even up to 3000 MHz !

UsingANRITSU RF Vector AnalyzerI did a lab measurements ofDirectivityof this knownRF SWR Bridge. So as we can see on the graph above we can use thisSWR RF Bridgeforideal measurementof well-matched devicesup to 1000 MHz. Thenup to 2500 MHzthis bridge can be used forreliable measurementand even up to3000 MHzit is usable forindicative measurement.

Not bad for such low cost device, isn't it ?

You can use it with HiQSDR or compatible SDR Transceivers with N2ADR software and NWT series of USB RF Analyzers or any other RF signal sources with detector.
