P波段微波注入反相器模数转换电路的响应
Response of analog-to-digital converter of three inverters to injection of P-band microwaves
摘要
Abstract
Microwave injection experiments were conducted on the analog-to-digital converter of three inverters to study its response to P-band microwaves of different parameters. The effectiveness and reliability of the experiments were achieved by using the eye figure to test the output performance and the temperature measurement circuit to check the operation stability, and analy zing the influence of different chips and printed circuit boards with statistical test. For injected pulse width above 70 ns, the threshold of the injected microwave power for noise margin of 50 ％ of the signal amplitude is 4 to 6 dBm lower than that for sampiing interval change of 10％; the power threshold for 30％ sampling interval change is 2 to 3 dB higher than that for 10％ change; the maximal nonlinear interference is 40％ sampling interval change for the microwave power less than 32 dBm. The threshold almost has no relation to the repetition frequency of the injected microwave. Additionally, for nonlinear interference, it has a strong relation to the pulse width of the injected microwave, with the inflection points of about 40 to70 ns.关键词
