MOTOROLA RF DEVICE DATA
APPLICATIONS INFORMATION
NOMINAL OPERATION
All electrical specifications are based on the nominal
conditions of Vs1 = Vs2 = Vs3 = 7.5 Vdc (Pins 2, 3, 4) and Pout
equal to 2 watts. With these conditions, maximum current
density on any device is 1.5 x 105 A/cm2 and maximum die
temperature with 100
°
C case operating temperature is
165
°
C. While the modules are designed to have excess gain
margin with ruggedness, operation of these units outside the
limits of published specifications is not recommended unless
prior communications regarding intended use have been
made with the factory representative.
GAIN CONTROL
The module output should be limited to 2 watts. The pre-
ferred method of power output control is to fix Vs1 = Vs2 = Vs3
= 7.5 Vdc (Pins 2, 3, 4), Pin (Pin 1) at 1 mW, and vary VCont
(Pin 1) voltage.
DECOUPLING
Due to the high gain of the three stages and the module
size limitation, external decoupling networks require careful
consideration. Pins 2, 3 and 4 are internally bypassed with a
0.018
μ
F chip capacitor which is effective for frequencies
from 5 MHz through 905 MHz. For bypassing frequencies
below 5 MHz, networks equivalent to that shown in Figure 1
are recommended. Inadequate decoupling will result in spu-
rious 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 equal to 10
Vdc, VSWR equal to 10:1, and output power equal to 3 watts.
