A Software-Definable RF Front End Module for LimeSDR Platforms

View all updates Jun 23, 2019

Crowdfunding Begins!

We are thrilled to announce the launch of our crowdfunding campaign for LimeRFE, a highly configurable RF front-end that provides multi-band power amplification (PA) and a low noise amplifier (LNA), plus filtering and support circuitry for use with LimeSDR, LimeSDR Mini, and LimeNET Micro.

LimeRFE features include software control of filtering for amateur radio bands spanning from HF to 3.5 GHz, plus cellular bands and a wideband mode for use with external filtering. It also supports bi-directional, level-shifted I/O that is capable of driving inductive loads such as coaxial relays.

Applications include amateur radio, cellular networks, and much more. LimeRFE takes low-cost, high-performance, incredibly flexible software-defined radio to the next level. We can’t wait to see what the community builds with the combination of LimeSDR/LimeNET Micro and LimeRFE!
