hittite t2200 series reverse engineer effort

[Aiy]

Hello Everyone,
I have an Hittite T2220 unit which is a sweet 10MHz - 20GHz synthesizer unit. As far as I can tell, the 20, 40 and 70GHz Hittite synthesizer units are universal for the 10M to 20G range. For the higher ranges, the units rely on an plug-in extender module to provide the extended frequency range(s).
I wonder if any (legendary) forum member would be willing to take their T2240 / T2270 unit apart and provide detailed photos of their synthesizer/ extender internals.
I asked Analog devices support for schematics / support in this pursuit, but they declined support on the grounds that:

Unfortunately  we are unable to share  these schematics as they  contain proprietary  IP  , in addition  many of the  key components are  now longer available and are now obsolete.
This is one of the reasons why we had  to discontinue this product line.

So, anyone keen on this pursuit?

Some pictures of the main PCB.
 I believe there are additional pictures on xdevs.

This article has a lot of VERY high resolution pictures, it seems that this a product based on Xilinx Spartan3 FPGA, some anemic NXP LPC arm MCU, for the front panel and GPIB and whole cornucopia of AD HW stuff, most likely long gone.

So what exactly you want to accomplish, reproduce those plugins, replace the firmware and make yourself a cool 70GHz generator  ? Not possible, because:

1) This is a strategic, export controlled thingie, and nobody will risk going on the ad side of uncle Sam.

2) Those generators are EXTREMELY rare, nobody sane will disassemble one of the 40/70GHz range risking destroying it (because if a mouse fart near those connectors, they will be unusable).

3) The stuff that was used was either never available for public (70GHz) or long gone (40GHz), so even if by miracle (not chance), someone will offer a plugin to disassemble and analyze, you won't be ever able to reproduce it.

Sorry to be a doomer, but after the experience with Anritsu and R&S synths, once is gone, is gone, if the defect is in SHF stages.
