DESCRIPTION
The UPG503B is a GaAs divide-by-4 prescaler that is capable
of operating up to 9 GHz. It is designed to be used in the
frequency synthesizers of microwave communication sys-
tems and measurement equipment. The UPG503B is a
dynamic divider. It employs buffered FET logic (BFL). The
UPG503B is available in a hermetic 8-lead ceramic flat
package.
