• RE: HMC576LC3B Layout problem

    Hi there,

     

    On the HMC576 (as well as the HMC507 which someone also inquired about recently) there are no internal connections to the N/C pins so they can be left floating (soldered to a pad of course) with no impact on RF performance.

     

    Unless there…

  • eliminating the hmc507 fo/2 harmonics

    How i can properly terminate the pins which oscillates at the frequency fo/2 so that unwanted spurs will not occur?

  • Operating HMC507 Below Spec 6.65GHz

    I am looking to buy a VCO that is stable between 6.5 and 7.0 GHz. I was looking at the HMC507 and the associated eval kit 110227-HMC507LP5 which shows a tuning of 6.65 to 7.65 GHz; but the datasheet has a plot showing tuning below 6.65 GHz. Will this VCO…

  • RE: Gerber Files for Catalog HMC VCO's in the LP5 package

    Yes of course.

    I should mention that many of Analog Devices' catalog microwave VCO's in the LP5 package share this same board including:

    HMC507 thru HMC515

    HMC529, HMC530,HMC531 & HMC534

    HMC1160 thru HMC1169

    These same files can be used…

  • 【在线研讨会讲义PPT下载】从0Hz到110GHz的全频谱RF信号链

    此次在线研讨会阐释了自收购Hittite Microwave后ADI的全新及扩展的RF能力。我们会举例说明ADI涵盖的更宽频谱范围及其真DC的重要性。信号链外的性能同样至关重要,展示低噪声、高稳定性控制和电源元件如何改善总体RF信号性能,并将讨论完整的信号链示例。

    主要讨论天线到比特和比特到天线,信号链覆盖,即刚才提到的从真正的DC 0 Hz到110 GHz的频谱覆盖。 我会简要介绍其中涉及到的各类设备。

    为什么良好的RF需要良好的电源,大家知道,RF需要干净的电源。然后,最后会和大家讨论“不止是芯片…

  • Equivalent Hours of HMC764LP6CE & HMC783LP6CE

    Dir Sir,

    I would like to know the equivalent hours of HMC764LP6CE & HMC783LP6CE. I cnn't find the information in the attached Reliability Report. How can I calculate that value?

    Best regards,

  • ADIsimPLL Transient Analysis

    Is there a way to extend time limit in ADIsimPLL? I am trying to evaluate loop filter BW vs. lock time. The tool limits time limit to 129uS while I'd like to see time extended to 1.5ms. Is there anyway to specify time step value so I can extend r=time…

  • 一文读懂锁相环(PLL)那些事

    锁相环(PLL)电路存在于各种高频应用中,从简单的时钟净化电路到用于高性能无线电通信链路的本振(LO),以及矢量网络分析仪(VNA)中的超快开关频率合成器。

    今天斑竹带来干货好文,参考上述各种应用来介绍PLL电路的一些构建模块,以指导器件选择和每种不同应用内部的权衡考虑,这对新手和PLL专家均有帮助。并且在文中参考了ADI公司的ADF4xxx和HMCxxx系列PLL和压控振荡器(VCO),并使用ADIsimPLL(ADI公司内部PLL电路仿真器)来演示不同电路性能参数。
