To our customers:

Due to circumstances beyond our control we have decided to discontinue quite a few of our products.

We will continue to build, calibrate, and repair our Research, Design, and Product Equipment.
This includes the 90IP, 90PF, 90PGA, 900CT, and 950 test equipment.

We have elected to leave the web page up with all of the discontinued products in case someone who has one of our products needs some information.

Frequency Devices will also continue to build and sell our Ham Radio Antennas.
Those antennas are available on Amazon or eBay or you can go to our antenna page here:

Frequency Devices has been in business since 1968 and has had many loyal customers over the years and we would like to thank them for their
business. It pains us to have to close the filter, oscillator, and amplifier portion of our business but it is unavoidable. If you have any
questions we can be reached at 815-434-7800.
