Abstract

A Ka-band HBT two-stage LNA has been developed. This circuit is to be used in a multifunction T/R module which includes both analog and digital functions. The measured noise figure is 5 dB from 30 GHz to 34 GHz, with an associated gain of better than 7.5 dB. A single-stage LNA has also been developed. The measured noise figure is 4 dB from 33 GHz to 35 GHz with an associated gain of 4 dB. These results are the best yet reported at Ka-band for a HBT LNA. The amplifiers have been designed to minimize the noise measure.

一个ka波段HBT两级LNA

已经开发了一种ka波段HBT两级LNA。该电路用于包括模拟和数字功能的多功能T/R模块中。在30ghz至34ghz范围内，测量噪声系数为5db，相关增益优于7.5 dB。单级LNA也已研制成功。从33 GHz到35 GHz测量噪声系数为4 dB，相关增益为4 dB。这些结果是迄今为止在ka波段报道的最好的HBT LNA。这些放大器的设计是为了尽量减少噪声。
