While talking about microwave prescalers, here's a 12 GHz prescaler project for the HP5328A frequency counter by Bert VE2ZAZ. Thje prescaler is based on the Hittite HMC363S8G div. by 8 12 GHz prescaler
http://www3.sympatico.ca/b.zauhar/hp5328a/hp5328a_prescaler.htm The page not only shows the construction of the prescaler itself, but also it's integration inside the 5328 counter and the rquired modifications of the HP counter. 73 de Normand Martel VE2UM Montreal, Qc.
