Building on the proven Airspy HF architecture, Airspy have designed the Most Refined HF/VHF SDR with world class performance in the smallest form factor.

The Airspy HF+ Discovery sets a new standard in terms of reception performance with extra pre-selector for all the supported bands and New DSP Core to optimize the gain distribution and the filtering parameters in real-time and dig deeper in the noise.

The signal path includes very high dynamic range data converters along with high performance passive mixers with an excellent Polyphase Harmonic Rejection structure.

The included band-tracking pre-selectors eliminate unwanted interference and preserve the dynamic range of the receiver. With its strong signal handling capability and incredibly Low Noise, it is the ideal companion for all your High Performance Receive Scenarios.

Both the architecture and level of integration achieved in this design allow Airspy to bring top performance reception at a very affordable price.
