RECOMMENDED
OPERATING CONDITIONS
Note: Because of the high internal gain and gain compression of the
UPB582, 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 UPB582 (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.

* Add a shunt resistor from the RF input line to ground. The
blocking capacitor should be between the resistor and the
UPB582, 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.
