摘要: 采用软件计算微带平面电感,描述了一款基于薄膜工艺的小型化宽带低噪声放大器的设计和性能。测试结果表明:在2.7~3.5 GHz的频段内,低噪声放大器的噪声系数小于等于0.55 dB,增益大于等于33 dB,增益平坦度小于等于±0.1 dB;在2~4 GHz的频段内,低噪声放大器的噪声系数小于等于0.65 dB,增益大于等于33 dB,增益平坦度小于等于±0.8 dB;尺寸为6.0 mm×4.2 mm。

Abstract: Design and performance of a wide band miniaturized low noise amplifier(LNA) working in S-band employing a method to calculate microstrip inductor are presented. The designed LNA working in the band of 2.7-3.5 GHz has a noise figure below 0.55 dB, and a small gain higher than 33 dB with flatness below ±0.1 dB. The designed LNA working in the band of 2-4 GHz has a noise figure below 0.65 dB, and a small gain higher than 33 dB with flatness below ±0.8 dB. The size of the LNA is only 6.0 mm×4.2 mm.

Key words: low noise figure, miniaturization, wide band
