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.
