A direct plugin solution seems to be difficult.? The grounding of
MMICs is quite critical and maybe you need to do some surgery on the
circuit to connect a daughter board that can be properly grounded
and route the signal using tiny coax cables.? Ready built complete
MMIC amplifiers can be purchased very cheap on eBay.

Thanks for the great replies! Some?have tried to identify
the original part, but none of the parts matched exactly.
The Avantek came closest, but these are apparently no
longer available?with bandwidth?above 1300 MHz.
Some have offered possible substitutes, but they either
do not have the bandwidth, or the pin outs are different
from the OEM part. This makes me?suspect that the OEM part
was truly a special part just for HP. The Keysight website
offers no substitute, but marks the part as "obsolete".
So at this point, the best route is probably to acquire a
modern MMIC and use a daughter board to connect to the
original board holes. It should be fairly easy with the
MIcrocircuit's amplifier. Except for the physical
connections, the design, supporting parts, and supply
voltage are very close to the original.
Thanks again for all of the great responses! I'll post
again when I have a working solution.
Best regards,
Joe, KN5U
