Title: Semiconductor phase shifter
Inventor: ORIME SHINKEI
IPC: H01P1/185
Filed: 1982-09-14
Abstract: PURPOSE:To prevent the deterioration of characteristics due to the variance of the FET characteristics, by using a low deadline type semiconductor phase shifter in which the drain and the gate of an FET are separated from each other with the source used in common. CONSTITUTION:An FET11 contains drain electrodes 12 and 13 as well as gate electrodes 14 and 15. In addition, a common source electrode 16 is connected to an earth conductor 2 by a pierced conductor 9. A conductor 17 is provided between branch lines 4 and then connected to the conductor 2 through the conductor 9. These lines 4 are connected to a main line 3 with a space of about 1/4 wavelength. The space between electrodes 12/14 and the electrode 16 is extremely reduced as well as between electrodes 12/13 and the electrode 16 respective by, to obtain similar characteristics among these electrodes. As the electrodes 12 and 13 are set extremely close to each other, the lines 4 are set close to each other. In this connection, the conductor 17 is provided to reduce as less as possible the connection between both lines 4. This arrangement enables the use of the FET11 containing the electrodes 12 and 13 put extremely close to each other, which is equal to the use of an FET that has an equal impedance to the microwaves between electrodes 12/16 and 13/16. Therefore this semiconductor phase shifter can prevent the performance deterioration due to the variance of the FET characteristics.
