ADI ADMV4530Ka频段卫星通信上变频器解决方案
ADI公司的ADMV4530是高度集成的上变频器,非常适合下一代Ka频段卫星通信的混频器.RF输出频传范围27GHz到31GHz,有两种上变换模式:差分基带I/Q(I/Q模式)直接上变换;单个上边带上变换(IF模式),1dB带宽为500MHz(I/Q模式),输入频率范围2GHz到3GHz(IF模式).可以使用一个 4 线串行端口接口 (SPI) 对该芯片进行编程.利用 SDP-S 控制器,用户可以通过 ADI 公司的分析控制评估 (ACE) 软件来连接 ADMV4530 SPI.主要用在卫星通信和点对点微波通信.本文介绍了ADMV4530主要特性,功能框图,以及评估板ADMV4530IQ-EVALZ/ADMV4530IF-EVALZE主要特性,ADMV4530IQ-EVALZ材料清单,ADMV4530IQ-EVALZ电路图和ADMV4530IF-EVALZ E电路图,以及PCB设计图.
The ADMV4530 is a highly integrated upconverter with an inphase/quadrature (I/Q) mixer that is ideally suited for next generation Ka band satellite communications.
An integrated low phase noise, fractional-N phase-locked loop (PLL) with a voltage controlled oscillator (VCO) and internal 2× multiplier generate the necessary on-chip local oscillator (LO) signal for the I/Q mixer, eliminating the need for external frequency synthesis. The VCO uses an internal autocalibration routine that allows the PLL to select the necessary settings and locks in approximately 100 μs.
