New Spyverter SDR Upconverter Software Defined Rec

New Spyverter SDR Upconverter Software Defined Rec Description

SpyVerter R2 builds on top of the successful SpyVerter architecture and improves some of the key points of high performance HF reception. We designed the SpyVerter R2 to extend the coverage of the Airspy receiver series to the HF down to virtually DC with world class dynamic range, frequency stability .
The architecture is still based on our switched double balanced mixer that moves the entire HF spectrum to the VHF band between 120 MHz and 180 MHz. We replaced the LO generator with a programmable, low phase noise PLL with 0.5 PPM VCTCXO. The Voltage control of this VCTCXO allows fine calibration of the operating frequency at the factory.
The embedded microcontroller provides both the programming of the PLL (Si5351C) and the voltage control via its embedded DAC. Once the DAC is settled and the PLL is programmed, the microcontroller enters a deep sleep mode to eliminate any interference.
We also added a 10MHz reference input clock for professional usages where phase coherency is required.
When used with an Airspy receiver, the SpyVerter R2 can be powered from the integrated Bias-Tee, and only uses ~10mA of current (versus 47mA in the old design).An extra USB power supply input is provided for compatibility with receivers like RTL-SDR.
