C波段程控移相器的研制

The Design of Program Controlled Phase Shifter in C Band

程控移相器广泛应用于微波系统中 ,在导弹仿真系统中应用尤为广泛 ,它的准确性、延迟性直接关系到整个导弹仿真系统的仿真结果 ,C波段程控移相器就是为此目的而设计的。程控移相器用程序控制移相器的偏置电路 ,运行程序可迅速地得到所需的移相度数。移相器设计时注意了线性度的补偿。测试结果表明 ,该移相器比普通电控移相器延迟小 ,准确度高 ,线性度好。

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.
