  • I am trying to sequence the HMC487 with HMC980

    I've used the HMC980 several times and it's a great chip.  With the amp HMC487 I can not get the drain to turn on if the gate (from HMC980) is connected.  If I add a separate negative supply to the amp gate Vd will turn on, but of course the automatic…

  • Problems when using HMC980LP4E eval board with HMC487LP5 eval board

    I have a HMC487LP5E (PA) evaluation board. When I use an adjustable voltage supply and follow the application note on how to bias the PA it works perfectly and draws the expected 1300 mA with a gate voltage of appoximately -0.2 V and a 7 V drain voltage…

  • RE: HMC995 and HMC980

    Hi,

    We have tested HMC980 with HMC995.

    The Igate for HMC995 typically stays within +-1.5 mA; hence you should not have any problems like the ones you had with HMC487.

    Let us know if you face any issues, we will provide the support.

    ps. I have also…

  • 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。

    主要挑战和系统设计考虑

  • 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.
