It is a 10Ghz transmitter receiver module.
Probably used as part of an automatic door opener system.

Dang don't think I'll be doing much with that but it was used to see if people was in the building
but they broke the rest of it that's all i could save LOL

Thanks

Nice datasheet.

Yes I think that the Gunn diode is the device in the centre of the waveguide cavity, but whether the resistor is there for static protection or just a leftover from where the thing was used I could not comment.

Dang you can't play with it without a....
As the datasheet dates from 1984, I suspect that such things have been licence free for many years now.

But rjenkins and I have both have licences which would cover it if adjusted to the frequency range 10.0 to 10.5 GHz.

Many burglar alarm PIR's also have radar modules now, plus the normal PIR type sensors - in order to avoid false triggering they require both sensors to be triggered. So if you wanted to play with a radar module, that would be a cheap way - and presumably licence free?.

Agreed. If you buy a dual mode sensor for an alarm system (which includes a 10GHz doppler sensor) there is no mention of any licensing requirement.

This is a current doppler radar type (the DT- one), 10.587GHz and has no requirements whatsoever for licencing..
