ADI ADMV4420 K波段下变换器解决方案
ADI公司的ADMV4420是集成了分数－N PLL和VCO的K波段下变换器,具有高度集成双平衡有源混频器和分数N合成器,其RF前端包括集成的平衡/不平衡变换器(balun)和低噪音放大器(LNA)(7dB单边带噪音),以及高动态范围IF输出放大器,其转换增益36dB.集成的低相位噪音分数N锁相环(PLL)和多核压控振荡器(VCO)和内部2x乘法器,输出P1dB为7 dBm,输出IP3为16 dBm,RF输入频率16.95 GHz 到 22.05 GHz, LO频率范围16.75 GHz to 21.15 GHz, IF频率范围900 MHz 到 2500 MHz ,5V工作电压,主要用在卫星通信和点对点微波通信.本文介绍了ADMV4420主要特性,功能框图以及评估板ADMV4420-EVALZ主要特性,配置图和实验室连接图,电路图,材料清单和PCB设计图.
The ADMV4420 is a highly integrated, double balanced, active mixer with an integrated fractional-N synthesizer, ideally suited for next generation K band satellite communications.
The RF front end consists of an integrated RF balun and low noise amplifier (LNA) for an optimal, 7 dB, single-sideband noise figure while minimizing external components. Additionally, the high dynamic range IF output amplifier provides a nominal conversion gain of 36 dB.
