ADI ADL5360高线性RF混频方案

ADI 公司的ADL5360是单路高线性双平衡RF混频器,RF频率从700MHz到1000MHz,IF频率从50MHz到350MHz,转换增益8.5dB,SSB噪音为9.5dB,输入IP3为26dBm,输入P1dB为10dBm,本地振荡(LO)驱动为0dBm,单端50欧姆RFR和LO输入端口,单电源3.3V到5V工作. ADL5360可广泛应用于蜂窝基站接收器,无线链接下变换器,卫星通信,点对点无线链接,仪表和军用设备等.本文介绍了ADL5360的主要特性,功能方框图以及评估板电路图和所用元件清单.

The ADL5360 utilizes two highly linear doubly balanced passive mixer cores along with integrated RF and LO balancing circuitry to enable single-ended operation. The ADL5360
incorporates two RF baluns allowing for optimal main and diversity mixer performance over a 700 to 1000 MHz RF input frequency range using low-side LO injection. The balanced passive mixer arrangement provides good LO to RF leakage, typically better than -25dBm, and excellent intermodulation performance. The balanced mixer cores also provide extremely high input linearity allowing the device to be used in demanding cellular applications where in-band blocking signals may otherwise result in the degradation of dynamic performance. High linearity IF buffer amps follow the passive mixer cores, to yield a typical power conversion gain of 9.5dB. (For a higher IIP3 version of the dual mixer without the IF amplifiers, please contact the factory)...
