Care and Feeding of Avantek YIG...

[artie]

Avantek Y089-4023, 8.0 - 20.0 GHz YTO

osc supply is marked, +15, and the FM and tune coils I can figure out.

But what's the heater voltage (and approximate current)?

THanks!

I have an old Avantek databook that lists YIG oscillators, but I don't
see that PN (I think it might be custom.) I only see one with that
tuning range -- AV-78020. Here's some of the data:

+15V @ 275 mA
Heater 20 to 28V, 1.5W at 25C or 2W at 0C
Power out to 50 ohm +13dBm
Main tuning 20 MHz/mA
FM tuning 450 kHz/mA

I'd guess yours is probably the same. This one is a round cylinder.
Pins clockwise from RF sma out are:

+15
Gnd
-5V but seems not used on this model
+FM
-FM
+Tune
-Tune
Htr
Htr

Hope it helps. Good luck.

Rex--

Thanks! That looks pretty good. The yig is a custom part, for HP. I
inherited a boat anchor with the yig, a 10811 timebase, and a bunch of
other goodies. The 10811 checks out fine. I'll have to haul the yig
into work, as I don't have anything other than diode detectors that go
above 4GHz.
