[hpsdr] New SDR chip from Analog

[Helmut, DC6NY]

Hi John,

Thanks for info. Yes, that’s an interesting chip, but IMHO not really
innovative except of the size of integration. Analogue down/up conversion
with all the known disadvantages is still necessary to cover the 4G and WIFI
frequency range of 1 to 5 GHz.  
There are only a few reasonably prized  High-Speed ADCs available like the
TI type ADC12D1800 to cover the entire frequency range between ‘0’ and 800
MHz in DDC/DUC technique. This would be together with following
filtering/decimation processing a real challenge for ham radio development.

Nevertheless I believe, we should start to develop intelligent applications
to protect higher ham bands against the appetite of commercial users maybe
in the first step with undersampling.

This looks like it would be an interesting chip to play for the higher 
frequencies:
