Abstract:
1. An electronic component for communication, comprising: a first power amplification circuit for amplifying an RF signal in a first frequency band to be transmitted; a second power amplification circuit for amplifying an RF signal in a second frequency band to be transmitted; a first terminal connected to a transmission/reception antenna; a second terminal connected to a first reception circuit for processing a received RF signal in the first frequency band; a third terminal connected to a second reception circuit for processing a received RF signal in the second frequency band; a first switch circuit provided between said first terminal and said first power amplification circuit and said second terminal; and a second switch circuit provided between said first terminal and said second power amplification circuit and said third terminal, wherein a frequency in said second frequency band has been adjusted to be lower than a frequency in said first frequency band, and a first signal line formed between said second power amplification circuit and the second switch circuit to propagate the RF signal to be transmitted has been designed to be longer than a second signal line formed between said first power amplification circuit and the first switch circuit to propagate the RF signal to be transmitted.
