摘要：<p>A first signal path has one or a plurality of coils (21, 22) arranged in series, the coils (21, 22) being connected to the output of a amplifier (31). A second signal path has the same number of coils (23, 24) as the coils of the first signal path, the coils (23, 24) being arranged in series and connected to the output of a second amplifier (32). Coupling paths have capacitors (25, 26, 27) and couple the first signal path and the second signal path at both ends (301 to 306) of the corresponding coils (21 to 24) on the first signal path and the second signal path. A SW controlling unit (3) switches a switch (400) to a contact (402) when a signal is input from the amplifier (31) and switches the switch (400) to a contact (401) when a signal is input from the second amplifier (32).</p>
