[time-nuts] Re: [OT] MB506 pre-scaler module ??

There are lots of newer, high performance prescalers available too, for 
the much higher frequencies - especially in GaAs and other technologies. 
Check this out:

Note that the architecture is basically the same as in the oldies. With 
the right combination of prescaler stages and baseband counting, you 
could conceivably build yourself a fairly decent 18 GHz CW microwave 
counter. Modern parts that are in production usually have evaluation 
boards available, so putting something together isn't too hard (but 
costs extra for convenient packaging).
