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 165°C. 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 µF 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.
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.
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.
