The RFGEN44 Packs a Microchip PIC16 and Analog's ADF4351 Into a Compact, Open Signal Generator

CircuitValley has opened crowdfunding for a battle-tested compact open-hardware signal generator, built around a Microchip PIC16 and Analog Devices' ADF4351 and designed to cover frequencies from 35MHz up to 4.4GHz: the RFGEN44.

"RFGEN44 is a fully open-source programmable RF signal generator," says company founder Gaurav Singh. "It is capable of generating frequencies up to 4.4GHz, and is controllable and programmable over USB. It’s perfect if you need a simple, driver-free, RF source when on the go. Designed to be cross platform, RFGEN44 can be used with most computers and is modifiable with Python. Thanks to its USB HID [Human Interface Device] support, you can integrate it into your workflow, making it available to scientific applications like Matlab. Built with reliable components from Analog Devices and Microchip, it’s as thoughtfully designed as it is easy to use."

The RFGEN44's compact chassis holds a custom board built around a Microchip PIC16 microcontroller...
