| Abstract: | The requirements for compact,high sensitivity,large dynamic range and wide frequency bandwidth of electronic equipment for radar reconnaissance applications have to be met.In the meantime,the designer is confronted with the challenges of complicated Electro Magnetic Interference（EMI） problems due to the mixed-signal design of high speed digital circuits and microwave analogue circuits.The main reasons regarding EMI problems in electronic equipment used for radar reconnaissance are investigated.Some practical and effective design approaches are proposed for improving Electro Magnetic Compatibility（EMC）. |
