摘要

我们介绍了在欧空局两个资格预审项目框架内开发的低噪声放大器(LNA)，用于METOP-SG卫星计划的54至229 GHz频率。这些卫星的主要目标是为业务天气预报和气候变化提供数据。具体来说，温度和水蒸气的测量只能通过推进当前的变质高电子迁移率晶体管(mHEMT)技术来实现。MMIC放大器基于In0.52Al0.48As/In0.8Ga0.2As/In0.53Ga0.47As异质结构，并使用栅极长度为50 nm的晶体管。将介绍所有频带的晶圆上测量以及封装lna的结果。

Low noise amplifiers for MetOp-SG

We present low-noise amplifiers (LNA) that have been developed in the framework of two pre-qualification ESA projects for frequencies between 54 and 229 GHz for the METOP-SG satellite program. The main goal of these satellites is to provide data for operational weather forecast and climate change. Specifically temperature and water vapor measurements can be only achieved by advancing the current state of the art for the metamorphic high electron mobility transistor (mHEMT) technology. The MMIC amplifiers are based on the In0.52Al0.48As/In0.8Ga0.2As/In0.53Ga0.47As heterostructure and utilize transistors with a gate length of 50 nm. On-wafer measurements will be presented for all frequency bands as well as results of packaged LNAs.
