| Abstract: | We describe a reflection type phase shifter which exhibits a large phase shift range. We characterized its response between 1.95 GHz and 2.15 GHz and achieved over 400/spl deg/ phase shift with less than 4dB insertion loss. The transition time from 0/spl deg/ to 180/spl deg/ is <20 nS. Our design is scalable to mm-wave operation because it uses no inductors. |
