Title: Compound semiconductor switch circuit device
Inventor: ASANO TETSUO
IPC: H01L29/812
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a compound semiconductor switch circuit device capable of outputting a required maximum power even when a gate width is 400 μm. SOLUTION: In the compound semiconductor switch circuit device, a design manner for widely securing the gate width Wg and reducing an FET on- resistance in order to reduce an insertion loss as less as possible is employed. In addition, means for obtaining a predetermined isolation with the gate width of 600 μm is also employed. However, there is a problem of the insufficient power output if the gate width is determined 400 μm for a chip size shrink. By noting a design wherein the isolation is secured by eliminating a shunt FET in a high frequency band over 2.4 GHz, further, an FET in a transmitting side and an FET in a receiving side are formed with asymmetrical circuits having different impurity concentration channel regions.  Thus, the circuit providing a predetermined isolation between both signal paths by reducing the gate width to 400 μm and reducing a capacitance component due to a gate electrode, and outputting the required maximum power output, is achieved.
