该rf3234是四波段(GSM850 / EGSM900/DCS1800 / PCS1900)有两个对称的接收端口和一个GSM / GPRS通信端口的高线性度12级标准的传输模块。该发射模块建立在RFMD的功率放大器与宏达®集成功率控制技术,PHEMT开关技术,并集成传输类的谐波性能滤波。结果是高性能,降低了解决方案的尺寸,并易于实现。该设备被设计用于作为的部分的发射机部分在GSM850 / EGSM900/DCS1800 / PCS1900和UMTS手机和消除了PA天线开关模块匹配网络的要求。该器件提供50?匹配的输入和输出端口,无需外部匹配元件。
The RF3234 features RFMD’s latest integrated power-flattening circuit, which significantly reduces current and power variation into load mismatch. Additionally, a VBATT tracking feature is incorporated to maintain switching performance as supply voltage decreases. The RF3234 also integrates an ESD filter to provide excellent ESD protection at the antenna port.
