Figure 55. Pulsed Bias at Low Duty Cycle

Transient thermal measurements and analysis were performed at

several different bias pulse widths and duty cycles to obtain the

thermal resistance values listed in Table 7.

The ADPA1106 amplifier is designed for a low duty-cycle pulsed ap-

plication. Under continuous bias conditions, the thermal resistance

increases to 6.5°C/W. Even at the nominal quiescent bias, VDD1

and VDD2 = 50 V and IDQ = 0.3 A, the 15 W power dissipation

results in a 97.5°C TCHAN rise above TCASE. If TCASE is 85°C, a

TCHAN of 182.5°C results if the device operates continuously.
