<p>PROBLEM TO BE SOLVED: To provide a communication unit such as a mobile phone that can realize enhancement of reception sensitivity and reduction in disturbance such as intermodulation and cross modulation at the same time. SOLUTION: A base band section 305 does not conduct simultaneous transmission and reception and uses changeover switches 101 and 107 performs control to select a circuit C2 when the level of a signal received by an antenna ANT1 or ANT2 is equal to or below a prescribed threshold value (XdB) and a bit error rate is equal to or below a prescribed threshold value (Y%) or control to select a circuit C1 in other cases.</p> |
