For V
SS1,
the bias voltage of -6.0 should be applied through a 2.2 V
Zener Diode (RD2.2FB or IN3394).
POWER SUPPLY CONFIGURATIONS
(V

are normally open)
Notes:
1. Because of the high internal gain and gain compression of the UPG503B, the device is prone to self-oscillation in the absence of an RF input
signal. This self-oscillation can be suppressed by either of the following means:
Add a shunt resistor to the RF input line. Typically a resistor value between 50 and 1000 ohms will suppress the self-
oscillation (see the test circuit schematic).
Apply a negative voltage through a 1000 ohm resistor to the normally open V
GG1
connection. Typically voltages between
0 and -9 volts will suppress the self-oscillation.
Both of these approaches will reduce the input sensitivity of the device (by as much as 3 dB for a 50 ohm shunt resistor), but otherwise have no
effect on the reliability or electrical characteristics of the device.
