MAX2045/MAX2046/MAX2047低成本全集成矢量乘法器用来改变RF信号的幅值与相位。各款器件分别为UMTS (MAX2045)、DCS/PCS (MAX2046)或蜂窝/GSM (MAX2047)频段而优化。这些器件都具有差分RF输入与输出。
MAX2045/MAX2046/MAX2047通过差分I/Q放大器提供矢量调节。I/Q放大器可以与电压和/或电流型数模转换器(DAC)接口。电压输入端针对与电压模式DAC接口而设计,而电流输入端针对与电流模式DAC接口而设计。对于使用单端电压型DAC的应用,还准备了内部2.5V参考电压。这些器件适用于CDMA、多载波CDMA、cdma2000?,以及WB-CDMA等应用。
MAX2045/MAX2046/MAX2047工作在4.75V至5.25V单电源下。所有器件都采用紧凑的5mm x 5mm,32引脚薄型QFN底盘裸露的封装。
The MAX2045/MAX2046/MAX2047 low-cost, fully integrated vector multipliers alter the magnitude and phase of an RF signal. Each device is optimized for the UMTS (MAX2045), DCS/PCS (MAX2046), or cellular/GSM (MAX2047) frequency bands. These devices feature differential RF inputs and outputs.
The MAX2045/MAX2046/MAX2047 provide vector adjustment through the differential I/Q amplifiers. The I/Q amplifiers can interface with voltage and/or current digital-to-analog converters (DACs). The voltage inputs are designed to interface to a voltage-mode DAC, while the current inputs are designed to interface to a currentmode DAC. An internal 2.5V reference voltage is provided for applications using singleended voltage DACs
.The MAX2045/MAX2046/MAX2047 operate from a 4.75V to 5.25V single supply. All devices are offered in a compact 5mm 5mm, 32-lead thin QFN exposed-paddle packages.
