FEATURES

ELECTRICAL CHARACTERISTICS

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.

TEST CIRCUIT

*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:

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.

INPUT

= 5 V)

* 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.
