a little over $5 apiece. If you haven't found it already, there's an HP/JDEC reference available. Sphere has one: That's pretty useful. On Wed, Sep 04, 2019 at 01:18:46PM -0700, pa0vtw@... wrote:

I have a bunch of SD211DE and some SD214DE. I wonder what both of those are used in/for.

I remember having used Dual gate DMos fets in a 2m converter. It was considered state of the art over conventional dual gate mosfets like 40673. SD211 are single gate DMos fets....

Siliconix DMOS FET's were used for high level (+27) mixers in HF receivers.? Racal 6790, 6830 etc.? 4 were used in a commutating ring setup driven by an amp driven to 1dBc to get a flat top on the 70 MHz sine wave. Siliconix did a good white paper on the application. Tektronix used DMOD in the front ends of some TM500/5000 counters, DC509 etc. JimMc
