| 2.5 GHz DIVIDE- BY- 512/256 PRESCALER FEATURES * HIGH FREQUENCY OPERATION TO 2.5 GHz * WIDE BAND OPERATION * SINGLE SUPPLY VOLTAGE: VCC = 5 V 10% * AVAILABLE IN TAPE AND REEL (G08 PACKAGE) INPUT 2200 pF* 1 2200 pF 2 3 2200 pF 4 UPB586B UPB586G TEST CIRCUIT M VCC 2200 pF 8 2200 pF 7 6 5 OUTPUT DESCRIPTION The UPB586 series of devices are silicon bipolar prescalers which can be operated in divide-by-256 or divide-by-512 mode. They feature high frequency response and operate from a single 5 volt supply. The series is available in two package styles: 8 lead ceramic flat pack (UPB586B) and an 8 pin plastic mini-flat package (UPB586G). Applications include frequency synthesis, division and scaling. *Not required if M is grounded. Note: Because of the high internal gain and gain compression of the UPB586, 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 UPB586, 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 +3.0 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 +1.5 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 UPB586 (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.
