It is intended to be used in frequency synthesizers of microwave communications systems and measurement equipment. The UPG501B is a static divider with two (2) master-slave D-type flip-flops using SourceCoupled-FET-Logic (SCFL). It operates from a single supply voltage. The UPG501B is housed in a hermetically sealed 8lead ceramic flat package that is easy to use and provides high reliability.

TC 125C IN TYPICAL PERFORMANCE CURVES (TA = 25C) SSB PHASE NOISE vs. OFFSET FROM CARRIER fIN = 3.41 GHz, TA = 25C -70 Note: Because of the high internal gain and gain compression of the UPG501B, the device is subject 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). * Apply a negative voltage through a 1000 ohm resistor to the normally open VGG 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 other electrical characteristics of the device.
