Legacy Applications Information

In the design example, shown in FIgure 24, the operating

point is selected as a tradeoff between average power output

and quality of the AM.

For VCC = 3.0 Vdc;ICC = 18.5 mA and Imod = 0.5 mAdc

and a static DC offset of 1.04 Vdc, the circuit shown in

Figure 24 completes the design.

Where Rmod = (VCC – 1.04 Vdc)/0.5 mA = 3.92 kΩ, use a

standard value resistor of 3.9 kΩ.
