Abstract

A fully differential, high input power handling, ultra-wideband, variable gain low noise amplifier MMIC for a monostatic MIMO radar was designed in a 130 nm SiGe BiCMOS Technology. The amplifier features an extensively high RF input power survivability, high power handling, ultra-wideband operation of 0.1–50 GHz and a linearly variable gain with 12 dB tuning range. The measured differential mode noise figure is below 5.5 dB within the bandwidth, whereas the 1-dB compression point is reached at −7.8 to −2.6 dBm input power levels at nominal gain operation. The maximum DC power consumption is 70 mW and the total chip area is 0.76 mm2.
用于MIMO雷达应用的全差分高输入功率处理超宽带低噪声放大器
采用130 nm SiGe BiCMOS技术,设计了一种用于单站MIMO雷达的全差分、高输入功率处理、超宽带、可变增益低噪声放大器MMIC。该放大器具有极高的射频输入功率生存能力、高功率处理能力、0.1-50 GHz的超宽带工作以及12 dB调谐范围的线性可变增益。在带宽范围内,测量的差模噪声系数低于5.5 dB,而在标称增益操作下,在- 7.8至- 2.6 dBm输入功率水平下达到1 dB压缩点。最大直流功耗为70mw,总芯片面积为0.76 mm2。
