VXSDR Microwave Software Defined Radios

Picture of the VXSDR-20 boards

The VXSDR-20-160 is the first member of the VXSDR family. It's a microwave software defined radio that transmits and receives from 5 to 20 GHz at 160 million samples per second. The next family member, the VXSDR-20-600, will have the same RF performance with larger bandwidth, at 600 million samples per second.

We designed the VXSDR-20 family 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.

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
