Product Description:
Airspy designed the SpyVerter R2 Upconverter to extend the coverage of the Airspy R2 and Mini series to the HF down to virtually DC with world class dynamic range, frequency stability and sensitivity to rival with high end analog designs at a very affordable price.

SpyVerter R2 builds on top of the successful SpyVerter architecture and improves the key points of high performance HF reception.

The architecture is based on our switched-mode double balanced mixer that translates 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.

An embedded microcontroller provides both the programming of the PLL (Si5351C) and the VCTCXO voltage control via its embedded DAC. Once the DAC is settled and the PLL is programmed, the microcontroller enters in a deep sleep mode to eliminate any possible interference with the reception.
