| 摘要 |
This invention relates to a high frequency switch circuit including a plurality of high frequency terminals (101, 102, 103) which input/output a high frequency signal, and a plurality of high frequency semiconductor switch sections (121, 122) which switch between these high frequency terminals. The plurality of high frequency semiconductor switch sections are isolated from each other in a DC state by a DC potential isolating section (131), and a DC potential opposite in level to a DC potential applied to a switching signal terminal (111, 112) arranged on the control side of each high frequency semiconductor switch section is applied to both or at least one of the input side and output side of each high frequency semiconductor switch section. <IMAGE> |
