摘要

本文介绍了一种多功能接收机的设计和特性,该接收机集成了用于LO产生的×4倍频器、图像抑制混频器和低噪声放大器。测量到的噪声系数为4.6 dB,功耗为140 mW。图像抑制优于47 dB,转换增益优于10 dB, IIP3优于12 dBm。这种性能远远优于任何可比较的现有发布的53 GHz接收器。所使用的工艺是商用的0.15µm GaAs mHEMT技术,ft=120 GHz, fmax=200 GHz。

A 53 GHz Single Chip Receiver for Geostationary Atmospheric Measurements
This paper presents the design and characterization of a multifunctional receiver with integrated ×4 frequency multiplier for the LO generation, image reject mixer and low noise amplifier into a single chip MMIC. Noise figure has been measured to 4.6 dB and power consumption to 140 mW. The image rejection is better than 47 dB, conversion gain 10 dB and IIP3 -12 dBm. This performance is far superior to any comparable existing published 53 GHz receiver. The process used is commercially available 0.15 µm GaAs mHEMT technology featuring ft=120 GHz and fmax=200 GHz.
