DESCRIPTION
The UPB587 series of devices are silicon bipolar digital prescalers which can be operated in divide-by-two, divide-byfour or divide-by-eight mode.
They feature frequency response to 1 GHz, and operate from a single 3 volt supply drawing only 5.
5 milliamps.
The series is available in two package styles: 8 lead ceramic flat pack (UPB587B), and an 8 pin plastic mini-flat package (UPB587G).
Applications include: synthesizer for DBS receiver and telecommunication applications.
The low DC voltage required and power-saving current draw make them ideal for hand-held, battery-powered applications.
