METHOD AND DEVICE FOR AUTOMATIC REGULATION OF TRANSMITTED POWER Russian patent published in 2001 - IPC

Abstract RU 2173501 C2

FIELD: transmitting stations of multiple- access code-dependent systems. SUBSTANCE: device depending for its operation on automatic regulation of high-frequency at sending station of multiple-access code-dependent system has at least one digital processing unit designed for coding data in transmission channel; transmitter used to convert, filter, and amplify output signals of digital processing unit; power amplifier intended to amplify transmitted signal to desired level for propagating amplified signal throughout open space; adjustable attenuator installed between transmitter and power amplifier and used to control transmitter output signal arriving at power amplifier; power meter that functions to measure transmitted power at power amplifier output; detector used to compare rated value of transmitted power with its measured value thereby detecting power setting error , if any; power regulation unit that serves to compare absolute power-setting error with preset permissible deviation and to control adjustable attenuator according to results of this comparison; and also coupler designed for connecting power amplifier to power meter. EFFECT: provision for regulating transmitted power by automatic control of high- frequency channels of this power. 3 cl, 2 dwg
