NXP 的LNA无线解决方案
NXP 无线模块BUF725 简介：
NXP的BUF725的可应用在GPS 的外置电线中。
其特点表现为：1）截止频率可以做到一百GHz以上， 可以很好的工作在10GHz频率以下。
2）与硅工艺兼容，易与CMOS 集成
3）相对GaAs，有成本优势
4）从性能来说，SiGe 射频器件噪声低，开关速度快，温度特性好，输出功率大，效率高。
特征描述：
The BFU725F/N1 is a wideband silicon germanium amplifier transistor for high speed,
low-noise applications. The transistor is designed to be used for LNA applications up to
15 GHz such as GPS, satellite radio, cordless phone, wireless LAN and satellite LNB. The
BFU725F/N1 is packaged in a SOT343F that has 2 emitter pins to reduce emitter
inductance (for maximum gain).
The BFU725F/N1 is ideal for applications where cost is a concern. It also gives thedesigner flexibility in his design work, for bias current, frequency of operation,noise-figure, gain and P1dB.
方案介绍：
The demonstration boardenables testing of the device performance and requires no additional support circuitry.
