I do agree with you. The pain is in the early stages of the

OK... So, linear operation does therefore seem to be the preferred
way to operate these MMICs rather than operation into compression.
That's what I seem to be observing if only because my final RF

Only beacuse I was more familiar with balanced doublers,
and felt that the x4 would need tougher filtering.
The balanced doublers also have much better conversion
efficiency, thus fewer gain stages. Or so I think.

Only purpose for this project is so that the Westminster clock chimes at the
same exact moment at the GPS driven UTC LED display in the lab shows the
quarter hour.
Why
Why not! :- )

ment racks I have and
see that at least the minute's digits read either: 00, 15, 30, or 45. And
FWIWthe LED display is driven by the NMEA data coming out of the GPS RX
inside a Z3810A.
How's that?

My E-bay FE-5680A finally arrived. (4weeks later)
Of the pins on the DB-9 connector, which one is the RF output?
The manual only talks about an SMA output.
I know this has been talked about before, but I cannot find the thread.
Thanks in advance & sorry for bandwidth,

Thank you though. Got it working fine thanks to all the answers and help!

GPS has its own time scale. Part of the GPS data stream contains the number
of seconds that GPS and UTC differ by.

Someone earlier today made the point
FWIWI used denatured alcohol and acetone. Just be sure to wear chemical
safe gloves and plenty of shop rags.
But it comes right off. Fumes are bad too.
Let the rags dry out before you put them in the trash.
