Abstract
Official abstract text for this publication.
A radio communication device includes an amplifier configured to amplify an electric signal to be transmitted; and a controlling section configured to set an operating point voltage of the amplifier to a first voltage for increasing a temperature in the amplifier in a non-transmission period after a reception period and before a transmission period and set the operating point voltage of the amplifier to a second voltage that is lower than the first voltage and higher than a pinch-off voltage in the transmission period.
First claim
Opening claim text (preview).
What is claimed is: 1 . A radio communication device, comprising: an amplifier configured to amplify an electric signal to be transmitted; and a controlling section configured to set an operating point voltage of the amplifier to a first voltage for increasing a temperature of the amplifier in a non-transmission period after a reception period and before a transmission period and set the operating point voltage of the amplifier to a second voltage that is lower than the first voltage and higher than a pinch-off voltage in the transmission period. 2 . The radio communication device according to claim 1 , wherein the first voltage is determined so as to ensure that an amount of heat generated from the amplifier in response to the first voltage in the non-transmission period is equal to the amount of heat generated from the amplifier in response to the second voltage in the transmission period. 3 . The radio communication device according to claim 1 , further comprising: a measuring section configured to measure a traffic amount of the electric signal to be transmitted, wherein the controlling section changes the first voltage based on the measured traffic amount. 4 . The radio communication device according to claim 1 , wherein the amplifier is a Field-Effect Transistor.
