【Abstract】 Program controlled phase shifter is widely applied in microwave system,especially in missile simulating system.The correctness and postponement of the phase shifter can affect the simulating results of the whole missile simulation system.Therefore,the phase shifter in C band is designed for this purpose.The bias circuit is controlled by the program.As soon as the controlling program has been run,the phase shift can be required.The linearity of phase shifter is compensated.The testing result shows that in contrast to common voltage controlled phase shifter the phase shifter can work more accurately and quickly,in addition,the linearity is better.更多还原
