[hpsdr] New chip

[Gerald Youngblood]

Alberto,
Yes, multiplication is a linear form of mixing so it should work.  I saw the
product announcement and thought the same thing.

> 
> The ADL5391 draws on three decades of experience in advanced 
> analog multiplier products. It provides the same general 
> mathematical function that has been field-proven to provide 
> an exceptional degree of versatility in function synthesis:
> 
> VW=a×(VXx VY)/1V + VZ

> The most significant advance in the ADL5391 is the use of a 
> new multiplier core architecture, which differs markedly from 
> the conventional form that has been in use since 1970. The 
> conventional structure, employing a current-mode, 
> trans-linear core, is fundamentally asymmetric with respect 
> to the X and Y inputs, leading to relative amplitude and 
> timing misalignments that are problematic at high 
> frequencies. The new amplifier core eliminates these 
> misalignments by offering absolutely symmetric signal paths 
> for both X and Y inputs. The Z input allows a signal to be 
> added directly to the output. This can be used to cancel a 
> carrier or to apply a static offset voltage.

> The ADL5391 is fabricated on Analog Devices' proprietary, 
> high performance 65 GHz SOI complementary SiGe bipolar IC 
> process. It is available in a 16-lead Pb-free LFCSP package 
> and operates over a -40°C to +85°C temperature range. 
> Evaluation boards are available.
