Re: HP YIG replacement 3-7GHz
|
Some of the agilent and rohde YTO were made by microsource , unfortunately microsource was bought out by gigatronics and I don¡¯t know if they still sell the YIGs as separate products ,? I expect for micro lambda to be tight lipped if it
comes to ¡°replacement¡± yigs as I know they make yigs for rohde and I assume also some for agilent and I am sure neither company would be happy if micro lambda were to undercut their spare part sales
?
As far as Avantek concerns you are talking about a entirely different generation of YIGs ,20MHz/Ma is actually common for tuning sensitivity of the main coil however agilent as well as WJ departed from this value !

Here is some info on the drivers

Hi Peter, Et al,
Sorry for the delayed response to all the positive comments. I have been away camping, soaking up what is left of the good weather in autumn, trying my new HF radio set up.
No doubt, there will be many challenges ahead, but I am determined to find a solution. I am waiting on a mail from Micro Lambda to see if they have ever made a replacement, the chap is going to ask the question for me, they have been so helpful to date. There
are other Micro Lambda models to suit Tek and R&S, so they have made replacement models for branded SA and Sign Gens. No harm asking.?
Peter, I think the original HP data sheet is right, this does represent a challenge at? or around 40MHz/mA, the hardware and software is tightly integrated, thus a YIG with similar spec or the development of an interface driver is needed. I haven't thought
that far ahead yet.
Like yourself, and I am sure others on the forum have purchased a YIG in the past to adapt, I purchased a Avantek Y084-1215 about 10 years ago, I recently tried to adapt via a crude interface driver, but this did not work out to well. Although the Avantek YIG
works extremely well for it's vintage, it's main coil spec is way out at ~22.4 MHZ/mA. In addition, getting the juice to run the heater from an internal supply is a challenge.
I am prepared to lay out the cash up to a point to develop a solution.
I hope I do not have to eat my words in time.
Stay tuned.
Regards
Gerald
