Abstract
When an antenna switching unit selects a first antenna and a reference gain does not exceed a first limit value, a gain of a variable amplifier is set to the reference gain. When the antenna switching unit selects the first antenna and the reference gain exceeds the first limit value, the gain of the variable amplifier is set to the first limit value. When the antenna switching unit selects a second antenna and the reference gain does not exceed a second limit value, the gain of the variable amplifier is set to the reference gain. When the antenna switching unit selects the second antenna and the reference gain exceeds the second limit value, the gain of the variable amplifier is set to the second limit value.
