Operating parameter control for a power amplifier |
| 摘要 |
A method of controlling operating parameters of a radio frequency power amplifier amplifying an input signal applied in bursts with controlled input power to an input of the power amplifier, comprising responding to gain variation parameters relating to variations in the scalar gain of said amplifier starting during an initial ramp-up period of a first burst to control supply voltage and quiescent current parameters for said amplifier during a subsequent burst. |

1. A method comprising:
controlling operating parameters of a radio frequency power amplifier amplifying an input signal applied in bursts with controlled input power to an input of the power amplifier; and responding to gain variation parameters relating to variations in a scalar gain of said amplifier starting during a first burst to control supply voltage and quiescent current parameters of said amplifier for a subsequent burst, wherein the gain variation parameters inc de a difference between a starting gain of the am lifter at a start of the initial ramp-up period and a peak gain of the amplifier during the initial ramp-up period of the first burst. |
