WIRELESS COMMUNICATION TERMINAL

摘要

A mobile communication terminal (100) has a switch (140A) that switches to either a path (T2) that supplies a transmission signal from a modulator-demodulator circuit (200) to a transmitting and receiving antenna (101) via a transmission filter (110A) and via a notch filter (120A) or a path (T1) that supplies the transmission signal to transmitting and receiving antenna (101) via the transmission filter (110A) and a switch (140B) that switches to either a path (R2) that supplies a reception signal from transmitting and receiving antenna (101) to the modulator-demodulator circuit (200) via a reception filter (110B) and a notch filter (120B) or a path (R1) that supplies the reception signal to the modulator-demodulator circuit (200) via the reception filter (110B).
