UPB587B* 1.0 GHz DIVIDE- BY- 2/4/8 PRESCALER UPB587G *B VERSION FOR HI-REL APPLICATIONS ONLY FEATURES TEST CIRCUIT VCC • HIGH FREQUENCY OPERATION TO 1 GHz • LOW SUPPLY VOLTAGE: 2.2 V to 3.5 V C C • LOW SUPPLY CURRENT: 5.5 mA • AVAILABLE IN TAPE AND REEL (G08 PACKAGE) 8 2 7 C C INPUT 1 OUTPUT M2 C 3 6 4 5 Re* Ro* C 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. M1 C C = 2200 pF *Re and Ro used on test circuit as indicated below.

TOP UNITS RATINGS Supply Voltage PARAMETER V 2.2 to 3.5 Operating Temperature °C -20 to +75 Note: Because of the high internal gain and gain compression of the UPB587, this device is prone to self-oscillation in the absence of an RF input signal. If the device will be used in an application where DC power will be applied in the absence of an RF input signal, this self-oscillation can be suppressed by any of the following means: * Add a shunt resistor from the RF input line to ground. The blocking capacitor should be between the resistor and the UPB587, but physical separation should be minimized. Typically a resistor value between 50 and 100 ohms will suppress the selfoscillation. * Apply a DC offset voltage of +2.0 volts to the INPUT pin. The voltage source should be isolated from the INPUT pin by a series 1000 ohm resistor. * Apply a DC offset voltage of +1.0 volts to the BYPASS pin. The voltage source should be isolated from the BYPASS pin by a series 1000 ohm resistor. All these approaches reduce the input sensitivity of the UPB587 (by as much as 3 dB for the example of a 50 ohm shunt resistor), but otherwise have no affect on the reliability or other electrical characteristics of this device.
