    Abstract
    When examining a monthly bank account statement it is not only the number below the bottom line that matters. Whether that number has a minus or plus in front of it is also crucial. For many technical issues, the sign matters as well. In circuits, we can change the sign of the RF signal by means of phase shifters. Moreover, by using phase shifters, intermediate states between the signs (including complex values) can be set in circuits With the increasing use of wireless systems in GHz range, there is high demand for integrated phase shifters in phased arrays and MIMO on chip systems. An analog phase shifter has been designed and analyzed to meet the needs of Radar and Telecom applications. An X-band (8- 12 GHz) analog phase shifter using vector modulator principle is designed and analyzed using microstrip planar trans- mission line. The output of phase shifter at 0, 10, 45, 90, 135 and 180 has phase error in the range of 5. The input return loss is in the range of 5-7 dB and the output return loss is in the range of 5-15 dB. Also the insertion loss of the designed phase shifter is in the range of 5-8 dB. The designed phase shifter is then compared with commercially available Hittite's analog phase shifter
