• RE: I am looking for a voltage controlled Oscillator (VCO) in the frequency range 0.5 GHz - 4.5 GHz and to be operated (controlled) using a PWM from an MCU. Any suggestions?

    Hi,

    Unfortunately we don't have any stand alone, varactor tuned oscillators that specifically cover that range. A good solution that minimizes complexity would be the HMC586 (4.0 GHz to 8.0 GHz ) VCO followed by the HMC862A (Div 1/2/4/8) frequency divider…

  • Can HMC856 works with positive supply?

    HMC856 has two power supply, GND and VEE(-3.3V). Can I connect the GND pin to positive supply(+3.3V) and connect the VEE pin to ground? In my appilcation, the LVDS signal from the FPGA should be changed to the negetive CML level through a logic level…

  • RE: DDS drive PLL

    The 5356 is a multi band VCO which won't easily allow these types of sweeps. You need the HMC586 which is a truly wideband part, along with a PFD or other external PLL like the ADF4107.

  • HMC587 Eval Board Stack Upand and Layout

    Hi all,

    I have something confusing with my HMC586 pcb board. Could anybody please give me information about the stack up and layout of the HMC587 eval board?

     

    Thank you .

    Best Regards,

    Alex

  • RE: HMC704的调试

    压控端有电压,看看VCO的供电是否正常,有可能HMC586的电源脚虚焊了。先把这个问题解决了在解决后续的问题。HMC704的CP端能输出的电压是根据你的VP端给的电压相关的。

  • RE: HMC883

    The HMC833LP6GE PLLVCO does not provide any internal sweep functionality.  This capability was included with the HMC701, HMC702 and HMC703 but these are PLL only parts.  You can use a wideband external VCO to cover some of your 25-6000MHz band, for example…

  • Loop Filter for HMC439QS16G

    Hello,

    I have HMC586LC4B (VCO), HMC434 (Freq Divider by 8), and HMC439QS16G (PFD). I want to build FMCW chirp 4.5 - 5.5Ghz and I have generated chirp 562.5 - 687.5 MHz as reference. But I have no idea about designing the Loop Filter to bridge my PFD and…
