APPLICATIONS INFORMATION
NOMINAL OPERATION All electrical specifications are based on the nominal conditions of Vs1 = Vs2 = Vs3 = Vs4 = 12.5 Vdc (Pins 2, 3, 5, 6), and Vb = 5.0 Vdc (Pin 4). With these conditions, maximum current density on any device is 1.5 x 105 A/cm2 and maximum die temperature is 165C. While the modules are designed to have excess gain margin with ruggedness, operation of these units outside the published specifications is not recommended unless prior communications regarding intended use have been made with the factory representative. DECOUPLING Due to the high gain of the four stages and the module size limitation, external decoupling networks require careful consideration, Pins 2, 3, 4, 5, and 6 are internally bypassed with a 0.018 F chip capacitor which is effective for frequencies from 5.0 MHz through 940 MHz. For bypassing frequencies below 5.0 MHz, networks equivalent to that shown in Figure 1 are recommended. Inadequate decoupling will result in spurious outputs at certain operating frequencies and certain phase angles of input and output VSWR. LOAD MISMATCH During final test each module is load mismatch tested in a fixture having the identical decoupling networks described in Figure 1. Electrical conditions are Vs1 = Vs2 = Vs3 = Vs4 = 15.6 Vdc (Pins 2, 3, 5, 6), and Vb = 5.0 Vdc (Pin 4), VSWR equal to 10:1, and output power equal to 40 watts.
GAIN CONTROL The module output power should be limited to specified value. The preferred method of power control is to fix Vs1 = Vs2 = Vs3 = Vs4 = 12.5 Vdc (Pins 2, 3, 5, 6), Vb = 5.0 Vdc (Pin 4), and vary Pin (Pin 1) from 0 to 100 mW.
