The Z10050A is a 3dB hybrid coupler, to be used to split a signal into two paths (to connect two receivers to one antenna, for example) or to combine two signals into one (two signal generators combined for intermodulation testing, most commonly).

I decided not to make the Z10050A a full kit because it's too labor intensive for me, particularly if bought assembled.

There's still interest in an inexpensive 3-dB hybrid coupler, so I've decided to make the hard to find parts available as a "parts only" kit. These include all the electronic parts needed to make the coupler. The builder is responsible for an enclosure and three connectors of choice.

The kit does not include a printed circuit board because it's simple enough not to need one and in fact the coupler has a bit better port-to-port isolation when built with the parts hanging in air.

Photos of customer builds are at the bottom of this page.

I've written an 8-page "Notes on Building the Z10050A" manual for the parts kit, with illustrations on how to build a coupler with the parts, as well as measurements on a sample coupler. Click here to read the manual. The Z10050A is quite a decent performer, as good as a similar Mini-Circuits coupler in my measurements.

The Z10050A  parts kit is $5.00 for one, $9.00 for two. This price includes first class postage within the USA. DX prices are $6.00 for one, $10.00 for two which includes first class (air) postage.
