ABSTRACT:
Provided are: at least one or more series variable resistors implemented by field effect transistors connected to a signal line A; and at least one or more shunt variable resistors implemented by field effect transistors connected between a signal outputting section A and a reference potential section GND. Further provided are: at least one or more series variable resistors implemented by field effect transistors connected to a signal line B arranged in parallel to the signal line A; and at least one or more shunt variable resistors implemented by field effect transistors connected between a signal outputting section B and a reference potential section GND.
