PURPOSE: A system and method for a wireless frequency switch are provided to test a wireless frequency switch. CONSTITUTION: One SPnT(Single-Pole n-Throw) switch serves frequency bands close to disturbance harmonics. The other SPnT switch serves frequency bands close to a signal generating unwanted harmonics. A filter(214) is connected between a high frequency band supporting SPnT switch(230) and an antenna port and removes a first frequency served by a low frequency band supporting SPnT switch(232). A filter(216) is connected between the low frequency band supporting SPnT switch and the antenna port and removes second harmonics of the first frequency served by the low frequency band supporting SPnT switch. [Reference numerals] (202, 204, 206, 208, 210, 212) Switch; (AA) High frequency band; (BB) Low frequency band; (CC) Antenna port
