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. *Re and Ro used on test circuit as indicated below.
