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.

The single-ended reference input to the PLL operates up to 500 MHz and features internal reference dividers and a multiplier for added flexibility. Additionally, the phase frequency detector (PFD) compa..
