Abstract

This paper presents the design and measured performance of an H-Band (220-325 GHz) submilimeter-wave monolithic integrated circuit (S-MMIC) implementing a balanced variable-gain low-noise amplifier (VGA) based on Tandem-X couplers for use in next generation communication systems. This amplifier will be used as first stage in an integrated wideband receiver for 300 GHz wireless communication for indoor environments. It provides low-noise pre-amplification as well as gain control in front of a quadrature down-conversion mixer.

采用串联- x耦合器的300 GHz多级平衡变增益放大器

本文介绍了一种h波段(220-325 GHz)亚毫米波单片集成电路(S-MMIC)的设计和测试性能，该电路实现了一种用于下一代通信系统的基于串联- x耦合器的平衡变增益低噪声放大器(VGA)。该放大器将作为集成宽带接收器的一级，用于室内环境的300 GHz无线通信。它在正交下变频混频器前提供低噪声预放大和增益控制。
