Single 400MHz Fixed Gain Amplifier
remain in the safe operating area. These parameters are
calculated as follows:
PDMAX for each amplifier can be calculated as follows:

VS = Supply Voltage
where:
TMAX = Maximum Ambient Temperature
qJA = Thermal Resistance of the Package
n = Number of Amplifiers in the Package
ISMAX = Maximum Supply Current of 1A
VOUTMAX = Maximum Output Voltage (Required)
RL = Load Resistance
PDMAX = Maximum Power Dissipation of Each
