Zusammenfassung:Wireless apparatus (100) includes radiation conductor (101) that radiates an electromagnetic wave including a high-frequency signal, power-limiting circuit (108), and high-frequency IC (106). In addition, power-limiting circuit (108) includes radiation conductor side impedance conversion circuit (102), wireless circuit side impedance conversion circuit (105), radiation conductor side power clipping diode (103), and wireless circuit side power clipping diode (104). In addition, radiation conductor side impedance conversion circuit (102) and wireless circuit side impedance conversion circuit (105) are connected between radiation conductor (101) and high-frequency IC (106). In addition, radiation conductor side power clipping diode (103) and wireless circuit side power clipping diode (104) are connected in parallel between radiation conductor side impedance conversion circuit (102) and wireless circuit side impedance conversion circuit (105).
