<P>PROBLEM TO BE SOLVED: To provide a high frequency switch capable of suppressing attenuation of a signal during reception while maintaining high connectability with other circuits without degrading passage and reflection characteristics during transmission even when characteristic impedance of a signal line is operated. <P>SOLUTION: A first transistor 4 is provided between a common terminal 1 and a reception terminal 3. A first high-frequency signal line 6 and a second high-frequency signal line 7 are connected in series to each other between the common terminal 1 and a transmission terminal 2. One end of a second transistor 5 is connected to a junction point between the first high-frequency signal line 6 and the second high-frequency signal line 7 and the other end of the second transistor 5 is grounded. <P>COPYRIGHT: (C)2013,JPO&INPIT |
