I have an HP 8553B RF section for the 141T spectrum analyzer with bad first mixer diodes I think.
The old HP part number is 08553-6002 CR3, CR4, CR5, CR6.
I found a place that says the replacement is HP 10514-8454. This is a matched quad set of diodes.
Does anyone know what a generic diode part would be for this?
Thanks
