RF POWER AMPLIFIER HAVING DISTRIBUTED MODULATION ENCODING

Title:

RF POWER AMPLIFIER HAVING DISTRIBUTED MODULATION ENCODING

Document Type and Number:

Japanese Patent JP2002009637

Kind Code:

A

Abstract:

To provide a system where modulation encode to control turn-on of power amplifier modules is conducted at each location.

This RF power amplifier system is provided with RF power amplifier modules and two encoders. Each encoder controls the operation of some of the power amplifier modules. Each encoder relates to different modules of the amplifier modules. An exciter receives an amplitude change signal and periodically provides a command signal to each modulation encoder, to instruct each modulation encoder as to how many modules are to be turned on among the related power amplifier modules as a function of the value of an input signal. Each module encoder selects which of the related power amplifiers is to be turned on, in response to the command signal received.
