| 摘 要： | 采用Foundry提供的InGaP/GaAs HBT工艺设计了一种数字静态除2高速预分频器MMIC.流片测试结果与仿真结果基本吻合,最高工作频率高于仿真结果.设计过程在速度和功耗之间进行了折中,并且考虑了自谐振频率对电路的影响.测试结果显示:在5V电源电压下,该预分频器静态电流为60mA,最高工作频率达到15GHz,自谐振频率为19.79GHz.该MMIC可以直接应用到S-X波段射频微波系统中.

| Abstract: | A digital static divided-by-2 high speed prescaler MMIC was designed using the InGaP/GaAs HBT process provided by the Foundry.The test results are almost consistent with the simulation results,and the highest frequency that the prescaler can work is beyond the simulation result.In the design process,the trade-off between speed and power was considered,and also the influence of self-oscillation frequency to the circuit.The test results show that under a supply voltage of 5 V,the static DC current of the prescaler is 60 mA,and the highest frequency that the prescaler can work is 15 GHz,and the self-oscillation frequency is19.79 GHz.This MMIC can be directly used in S-X band RF/MW system. |
