Title:
【発明の名称】増幅の自動適合バイアスを備えた変調無線信号送信器
Document Type and Number:
Japanese Patent JP2003510874
Kind Code:
A
Abstract:
The invention relates to a transmitter of radio signals (SMS), which are amplitude-modulated according to a discrete plurality of amplitude levels, in which at least one output power transistor ( 6 ) receives, on one of its terminals, a bias-voltage level which is adapted to the amplitude level represented by the instantaneous value of a selection signal (SS) generated by analysis means ( 11 ) on the basis of the digital control signals ( 1 ). The electrical consumption is hence optimized.
