That would be a Motorola MV1650 or equivalent. You may have to select
for 100pf +/- 5% @ 4V as the standard spec is 10% but it probably does
not matter as the tuning ratio will be greater than the >2 spec.

Hello,
I found the 10811 in my 8662A to be quite noisy and was able to trace
the problem down to the tuning diode.
Actually, the phase noise started to jump when the oven heated up. As
a quick solution, I replaced it with a SMD type that I had at hands.
I would appreciate any hint where to find an original diode (even
though I could leave it as is).
As by the manual, the original is a '0122-0244 DIODE-VVC 100PF 5%
C4/C25-MIN=2 BVR-30V Mfr. 28480'
Mfr. 28480 is listed as HP, but the diode is marked 'M' for Motorola
and '0244' and '312'.
