The UPG503B is a GaAs divide-by-4 prescaler that is capable
of operating up to 9 GHz. It is designed to be used in the
frequency synthesizers of microwave communication systems and measurement equipment. The UPG503B is a
dynamic divider. It employs buffered FET logic (BFL). The
UPG503B is available in a hermetic 8-lead ceramic flat
package.

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 selfoscillation (see the test circuit schematic).
• Apply a negative voltage through a 1000 ohm resistor to the normally open VGG1 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.
