摘　　要：小体积、低功耗、宽频带是低噪声放大器发展的重要方向。本文设计了一个基于LTCC技术的宽带低噪声放大器,运用LTCC的高集成特性对匹配电路进行内埋置,并对电源杂波进行抑制,在保障性能的条件下最大限度缩小了体积。该放大器在工作频率0.2GHz～4.1GHz范围内体现了小体积,低功耗,低噪声,宽频带的特性,适用于该频段各种接收前端。Small size,low power and broad band are the main development trends of low noise amplifier.A broadband LNA based on LTCC technology is presented in this paper.With LTCC high-integrated characteristic,matching circuits are embedded in the substrate,power noise is restrained and the volume is farthest reduced.The results show a LTCC LNA with broad band,small size,low power,and low noise from 0.2 to 4.1GHz,thus suitable for various receiver front-end in this band.
