DESCRIPTION
The UPG501B is a GaAs divide-by-4 prescaler that is capable
of operating up to 5 GHz. It is intended to be used in frequency
synthesizers of microwave communications systems and
measurement equipment. The UPG501B is a static divider
with two (2) master-slave D-type flip-flops using Source-
Coupled-FET-Logic (SCFL). It operates from a single supply
voltage. The UPG501B is housed in a hermetically sealed 8-
lead ceramic flat package that is easy to use and provides high
reliability.
