Patent ID: 8193860

Claim:
A method for automatically controlling an operation of a DC power enhancement circuitry connected to an RF power amplifier (PA) that operates at various input signal levels, comprising: a) Continuously sensing an instantaneous magnitude of said input signal by a coupler, which is followed by a detector and storing said instantaneous magnitude and its highest peak; b) For a time period during which said peak remains the highest peak: b.1) determining the desired dynamic range of said power amplifier according to said peak; b.2) determining a corresponding threshold level and a gain of said enhancement circuitry for said time period; b.3) whenever said magnitude exceeds said corresponding threshold level, causing said enhancement circuitry to provide to said power amplifier a level of DC power enhancement required for maintaining the output power of said power amplifier within said output dynamic range; and c) whenever a higher peak is detected, repeating steps b.1-b.3) above for the time period during which said higher peak remains the highest peak of all preceding peaks and updating the value of the stored highest peak accordingly.
