Abstract
The power control profile of a power amplifier circuit has improved linearity by supplying an exponential current source. The current source is an exponent function of the control voltage. There is obtained improved linearity of the power output vs control voltage profile for the power amplifier circuit. Advantageously, the exponential current source provides for a temperature compensated power amplifier circuit as well as the circuit having improved performance for variations in a power supply voltage.
