DESCRIPTION

The UPG501B is a GaAs divide-by-4 prescaler that is capable of operating up to 5 GHz. 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 Source- Coupled-FET-Logic (SCFL). It operates from a single supply voltage. The UPG501B is housed in a hermetically sealed 8- lead ceramic flat package that is easy to use and provides high reliability.

T C ≤ 125°C ABSOLUTE MAXIMUM RATINGS 1 (TA = 25°C) UPG501B TEST CIRCUIT TYPICAL PERFORMANCE CURVES (TA = 25°C) 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 self- oscillation (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. 10 100 1K 10K 100K Offset from Carrier (Hz) SSB Phase Noise (dBc/Hz) -70 -80 -90 -100 -110 -120 -130 -140 -150 -160 SSB PHASE NOISE vs. OFFSET FROM CARRIER fIN = 3.41 GHz, TA = 25°C TA = -25°C TA = +25°C TA = +75°C +20 +15 +10 -10 -15 -20 01 2345 67 Input Frequency, fIN (GHz ) VDD = +10V Output Power, POUT (dBm) OUTPUT POWER vs. INPUT FREQUENCY Case Temperature, TC (°C) Total Power Dissipation, PT (W) Tcase MAX = 125˚C 0 50 100 110 150 200 250 2.5 2.0 1.5 1.0 0.5 OUTLINE DIMENSIONS (Units in mm) UPG501B PACKAGE OUTLINE BF08 LEAD CONNECTIONS: 5.
