摘要
给出了一种带有电流告警的集成低噪声放大器的设计方案和测试结果,采用集总元件和微带线混合匹配的网络,利用ADS软件完成设计和仿真。放大器在1710～1780MHz频率范围内,增益为16.5±0.5dB,噪声系数小于1dB,回波损耗大于20dB。测试结果满足给定指标的要求,证明了该设计方案的可行性。
A design scheme and test results of an integrated low noise balanced amplifier with current alarm are described.Matched networks are designed using a micro-strip and lumped elements structure.Circuit design and simulation are performed with ADS.The amplifier provides a gain of 16.5±0.5 dB,return loss of-20 dB and a noise figure below 1 dB in the frequency range of 1710~1780 MHz.Test results show that the circuit has met the specifications.
