<P>PROBLEM TO BE SOLVED: To enable a reception circuit which processes a plurality of reception signals, to use a differential input/output type low-noise amplifier, and to make the reception circuit compact and inexpensive by decreasing the number of low-noise amplifiers. <P>SOLUTION: The high frequency electronic component 10 includes a switch 11 and a balun 12. The switch 11 performs switching between a reception signal GSM Rx1 in the form of an unbalanced signal received at an input port 11a and a reception signal GSM Rx2 in the form of an unbalanced signal received at an input port 11b, and outputs one of the signals from an output port 11c. The balun 12 converts the reception signal in the form of an unbalanced signal output form the output port 11c to a reception signal in the form of a balanced signal, and outputs this signal to a differential input/output type low-noise amplifier 14. <P>COPYRIGHT: (C)2009,JPO&INPIT |
