2.5 GHz UPB586B
DIVIDE- BY- 512/256 PRESCALER UPB586G
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)
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 scal-
ing.

*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 self-
oscillation.
* 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.
