设计了一个倍频程带宽的单脉冲处理器，工作频率为2 ~ 4GHz。该设计是基于一种新的架构，其中两个90/spl度/延迟线和0 dB耦合器中使用的单脉冲电路。在差端口中获得2- 4GHz带宽，其中由于两个90/spl deg/延迟线而引起的色散被抵消。仿真结果表明，当使用Lange耦合器进行0/spl deg//90/spl deg/混合时，在2 GHz带宽上的零陷深度为20 dB，总变化为1 dB。单脉冲处理器制作在510 /spl μ/m高阻硅衬底上。测量结果表明，在2 GHz带宽上的18 dB零值和在以2.6 GHz为中心的0.95 GHz带宽上的30 dB零值，和模式中有2 dB的变化。这种新型单脉冲电路可用于毫米波宽带雷达（8-16 GHz，20-40 GHz）或新型中频单脉冲系统。
An octave bandwidth monopulse processor has been designed to operate from 2 to 4 GHz. The design is based on a new architecture in which two 90/spl deg/ delay lines and a 0 dB coupler are used in the monopulse circuit. The 2-4 GHz bandwidth is obtained in the difference port in which the dispersion due to the two 90/spl deg/ delay lines cancels. The simulated results demonstrate a 20 dB null depth over a 2 GHz bandwidth and a sum variation of 1 dB when using Lange couplers for the 0/spl deg//90/spl deg/ hybrid. The monopulse processor was fabricated on a 510 /spl mu/m high resistivity silicon substrate. The measured results indicate an 18 dB null over a 2 GHz bandwidth and a 30 dB null over a 0.95 GHz bandwidth centered at 2.6 GHz with a 2 dB variation in the sum pattern. This novel monopulse circuit can be used in millimeter-wave wideband radars (8-16 GHz, 20-40 GHz) or in novel IF-based monopulse systems.
