• RE: Problems about high performance clock generators such as HMC830,HMC831,HMC832,HMC1034,HMC1035

    When operating in 'fundamental' mode (which is >=1500MHz) with HMC830, HMC832, HMC1034 & HMC1035 the output is a sine wave.  When operating in 'divider' mode (<1500MHz) the output is a square wave with nominal 50% duty cycle.

  • HMC831配置始终失败

    硬件电路完全参照评估版原理图所设计的。

    我们仔细研究了HMC831的相关寄存器,但始终无法输出正确的频率。输出有时输出1.85GHz,有时输出2.09GHz。下面是我们配置的寄存器。

  • RE: HMC832 PLL

    Both HMC830 and HMC832 will meet these requirements but the application must utilize a tunable reference and manual tuning to meet the -60dBc spurious and hop time requirements.  I've attached an appnote on manual tuning.  With a fixed 50MHz reference Figure…

  • HMC830 Frequency Hopping - Direct LUT ?

    Hello,

    I'm working with the PLL VCO HMC830.

    I want to use a look-up table (LUT) for manual calibration, as decribe in "Frequency Hopping with Hittite PLLVCOs Application Note" (attached) (https : // www . hittite.com/content/documents/application_notes…

  • Recommended regulators for ADI PLLs and VCOs

    PLL Recommended regulator
    Low power standalone PLLs and the ADF4360-x narrowband PLL/VCO family (< 100 mA); e.g. ADF41xx, ADF42xx, ADF4360-x

    Use the ADP150 regulator; good performance, low cost.

    Use…

  • 3月重点推荐——民用雷达解决方案,是你的菜么?

    雷达广泛用于民用应用,从执法部门实施的汽车系统和速度监控到空中交通管制、天气和海上监控。雷达发射无线电波,然后通过其路径中的物体反射。雷达接收机处理这些反射波以确定物体的范围、角度或速度。例如,海上雷达可测量船舶方位和距离以防碰撞并进行船舶导航。在港口或海湾处,船舶交通服务雷达系统用于监控和调节繁忙水域中的船舶运动。配合飞机应答机系统一起使用的类似民用空中交通管制雷达确定相似特性,以确保飞机之间保持安全距离并协调飞行路径。
