TRANSMITTER

To provide a technique capable of making the length of a coaxial cable between a transmission control part and a transmission high frequency part longer than standard specification.SOLUTION: In a transmitter, a transmission control part is connected to a transmission high frequency part including a power amplifier by a coaxial cable. The transmission high frequency part is provided with a target value table including setting information in order to correct a target value of output power of the power amplifier and the power consumption of the power amplifier. The transmission control part transmits setting information of special setting and a control signal including the target value of the output power of the power amplifier to the transmission high frequency part. The transmission high frequency part controls a protection function by increasing a correction amount of a cable loss of the coaxial cable on the basis of the setting information of the special setting. The transmission high frequency part sets the output power of the power amplifier to lower power on the basis of the target value of the output power of the power amplifier, and reduces the power consumption of the power amplifier in accordance with the setting information of the target value table.SELECTED DRAWING: Figure 7 【課題】送信制御部と送信高周波部と間の同軸ケーブルの長さを、標準仕様以上に長くすることが可能な技術を提供することにある。【解決手段】送信装置は、送信制御部と電力増幅器を含む送信高周波部との間が同軸ケーブルで接続される。前記送信高周波部は、前記電力増幅器の出力電力の目標値と前記電力増幅器の消費電力を補正する為の設定情報を含む目標値テーブルを備える。前記送信制御部は、特殊設定の設定情報と前記電力増幅器の出力電力の前記目標値を含む前記制御信号を前記送信高周波部へ送信し、前記送信高周波部は、前記特殊設定の設定情報に基づいて前記同軸ケーブルのケーブル損失の補正量を増加させることにより前記保護機能を制御し、前記送信高周波部は、前記電力増幅器の出力電力の前記目標値に基づいて、前記電力増幅器の出力電力を低電力に設定にし、前記目標値テーブルの前記設定情報に応じて前記電力増幅器の消費電力を減少させる。【選択図】図７
