Note: Because of the high internal gain and gain compression of the

UPB581, 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

UPB581, 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 UPB581 (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.
