The VXSDR-20 is a microwave software defined radio that transmits and receives from 5 to 20 GHz at 160 million samples per second. We designed the VXSDR-20 for the 5-20 GHz range where there aren't many cost-effective alternatives. It's similar to other commercial software defined radios, but covers the upper part of C band, all of X and Ku bands, and the lower part of K band (it's usable to 22 GHz). We made the design modular to support future versions with faster data transfer, higher sample rates, and extended frequency coverage.

We also have a related design for a block up- and down-converter, convenient for those who already have hardware and software for 6 GHz and below, and want to extend that up to 22 GHz. Please see the FAQ or email us if you're interested in converters.

The VXSDR-20's basic specifications are given on our specs page. If you'd like more information, you can ask a question on the questions page, or email us at
