• RE: VR connection for HMC745

    I liked to know why VR is connected to GND in HMC745 evaluation board.

    If VR is connected to GND, we don't have any output. right?

    In HMC744, HMC746,HMC748 evaluation board, Shorting VR is to VCC.

  • RE: Request mesuring data about jitter values of HMC744LC3 & HMC850LC3

    The worst case total jitter value for HMC744 and HMC850 is Tj = Dj + 2nRj = 6 + 0.2*7  = 7.4ps and cascaded is 10.4ps max for 1e-12 BER. Typically this value would be Tj=3.4ps for a single part and 4.8ps for cascaded.

  • 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。

  • RE: 36GHz RF oscillation signal source

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
