Radio frequency switching circuit and semiconductor device using the same
摘要:
A radio frequency switching circuit includes a plurality of input/output terminals for inputting/outputting a radio frequency signal and a plurality of basic switching sections each being provided between adjacent two of the plurality of the input/output terminals. Each of the basic switching sections includes three or more field effect transistors connected in series. Each of two of the field effect transistors connected in series which are located in both ends of the basic switching section, respectively, has a higher threshold voltage than respective threshold voltages of other ones of the field effect transistors.
