Abstract
A high frequency switch circuit including high frequency terminals which input/output a high frequency signal, high frequency semiconductor switch sections which are arranged on lines coupling the high frequency terminals, a DC potential isolating circuit which isolates the plurality of high frequency semiconductors switch sections from each other in a DC state, and DC potential transmission sections. Each DC potential transmission section couples a control side of an associated high frequency semiconductor switching section to at least one of an input side and an output side of another one of the plurality of high frequency semiconductor switch sections.
