Abstract
In a multicarrier amplifying device, a power detecting section of a variable frequency type changes a detection frequency according to a carrier frequency, a power of which is to be measured, to detect a power level of each carrier, and a controlling section automatically adjusts the power level of the carrier on the basis of the detected power level. It is possible to automatically set a transmission power level of one carrier to a specified power level without stopping existing carriers.
Claims3
A multicarrier amplifying device comprising:
- an amplifying means for amplifying a main signal having a plurality of carrier signals at frequencies differing from one another;
- a power detecting means of a variable frequency type being able to detect a power of an output of said amplifying means at an arbitrary detection frequency;
- and
- a controlling means for controlling said detection frequency in said power detecting means to a carrier detection frequency corresponding to a target carrier frequency, a power of which is to be measured, and controlling a power level of said carrier signal on the basis of a result of power detection by said power detecting means.
