I love to cook with wine. Sometimes I even put it in the food.
Only at audio frequencies :-( Further checking shows ridiculously wrong bias currents. Looks like all I managed to cure was Spice spitting out syntax and floating node errors :-(

AD834 is old and expensive!
Did you look at AN-212? It has a bunch of transistor-level detail.

AN-212 is an AppNote. Is there a better multiplier than AD834? I need good performance at 210MHz. ...Jim Thompson

Yes, I believe it is.
Is there a better multiplier than AD834? I
Tons of them. AD8343. ADL5391. Lots more.
Linear Tech. TI.
There are a bunch of IQ modulators that have built-in 90 degree phase shifters that work over a wide frequency range. I can't imagine how they manage that. TRF3701. LTC5588-1. ADL5386.
I'm considering using a fast multiplier, like the ADL5391, for my fast variable-height pulse generator, if I can't find a cheaper way to do it.

Informed by ADI that the AD834 model posted on the web "was not an official release", and I had an immediate need, I rolled my own...

For the moment LTspice _only_.
Comments most welcome, I want to get these sort of animals modeled correctly. ...Jim Thompson
