HIGH FREQUENCY SWITCHING CIRCUIT

PROBLEM TO BE SOLVED: To provide a high frequency switching circuit capable of preventing the generation of reverse bias in a transistor. SOLUTION: The high frequency switching circuit 1 includes first and second base grounding circuits 11 and 21, an emitter grounding circuit 31, first and second base switch elements 41 and 42, and first and second short circuit switch elements 51 and 52. Regarding the four switch elements, the ON/OFF states of the first and the second base switch elements 41 and 42 are made different from each other, the ON/OFF states of the first base switch element 41 and the second short circuit switch element 52 are turned to the same state, and the ON/OFF states of the second base switch element 42 and the first short circuit switch element 51 are turned to the same state.
