Analog Devices Inc. Analog Devices AD9364集成RF收发器
Analog Devices AD9364是高性能、高集成度射频捷变收发器™，设计用于3G和4G基站应用。该器件集RF前端与灵活的混合信号基带部分为一体，集成频率合成器。发射器采用直接转换体系结构，实现很高调制精度和超低噪声。自带发射(Tx)功率监控器可用作功率检波器，实现高精准Tx功率测量。完全集成锁相环为所有Rx和Tx通道提供低功耗小数分频频率合成。集成所有VCO和环路滤波器组件。AD9364核心可由1.3V稳压器直接供电。集成电路通过一个标准4线串口和四个实时输入控制引脚控制。包含全面的关断模式，以降低正常使用过程中的功耗。Analog Devices AD9364的宽带能力使其成为多种收发器应用的理想选择。
The on-board transmit (Tx) power monitor of the AD9364 can be used as a power detector, enabling highly accurate Tx power measurements. The fully integrated phase-locked loops (PLLs) provide low power fractional-N frequency synthesis for all Rx and Tx channels. All VCO and loop filter components are integrated. The core of the AD9364 can be powered directly from a 1.3V regulator. The IC is controlled via a standard 4-wire serial port and four real-time input control pins. Comprehensive power-down modes are included to minimize power consumption during normal use. Analog Devices AD9364 wideband capability make it ideal for a broad range of transceiver applications.
