Avago 公司的MGA-16516是高线性低噪音配对GaAs MMIC放大器,采用Avago有所有权的0.24um GaAs 增强模式pHEMT工艺技术制造,每部分在850MHz是可提供17.7dB增益,0.4dB噪音,输入IP3为11.8dBm,在1dB增益压缩点的输出功率为18.3dB,主要用在GSM和CDMA蜂窝设备的低噪音放大器和其它超低噪音放大应用.本文介绍了MGA-16516的主要特性, 简化电路图, 演示板电路图和元件列表以及演示板布局图.

MGA-16516: Low Noise, High Linearity Match Pair Low Noise Amplifier

Avago Technologies’ MGA-16516 is an economical, easy-to-use GaAs MMIC match pair Low Noise Amplifier (LNA). The LNA has low noise and high linearity achieved through the use of Avago Technologies’ proprietary 0.25um GaAs Enhancement-mode pHEMT process. It is housed in a miniature 4.0 x 4.0 x 0.85mm3 16-pin Quad-Flat-Non-Lead (QFN) package. The compact footprint and low profile coupled with low noise, high gain and high linearity make the MGA-16516 an ideal choice as a low noise amplifier for cellular infrastructure for GSM and CDMA. This device is applicable to both Single and Balance mode. It is designed for optimum use from 500MHz to 1.7GHz. For optimum performance at higher frequency from 1.7GHz to 2.7GHz, the MGA-17516 is recommended. Both MGA-16516 and MGA-17516 share the same package and pinout.
