I need to find replacement 1stmixer diodes for a HP8553 spectrum analyzer(110mhz)these parts are no longer made. Is a simple forward drop
matching good enough? How are these parts matched at the factory?
I have some 1n5711's are they OK or could someone recommend a
better part.

Thanks Joe wa9cgz

If you could identify what you're looking for, I might be able to help. I have a good number of matched pairs.

The original part# was 5082-0271 I can't find any info about it
other than the where part of a matched quad.
In looking over the data sheets the 2811 or 2835 schottky would
may work but I may need to quad match them.
