• HMC703+HMC733输出0.1-21GHz


    我在用HMC703+HMC733输出0.1-21GHz时,发现在VCO输出频率在高于18GHz后,将带宽span设置为10k时,输出信号底噪不停抖动,且输出相位噪声恶化严重,请问是什么原因造成的,LPF采用100k有源设计??

  • hmc704+op27+hmc733 频综调试

    我的频综采用hmc704+op27+hmc733设计,环路用的是增益结构,从正输入,怎么调试都锁不住!频率打算出19ghz。请问问各位高手是不是这个运放选择的实现不了呢?

  • HMC733+ADF41020  目前遇到的问题

    请问有没有谁用过HMC733+ADF41020?我目前遇到的问题,出10~18GHz,会有个1/2信号,但是HMC587+ADF41020就没有1/2杂散,是怎么回事呢?

  • HMC733 tune voltage range for 10-20GHz operation

    If I had a rail to rail opamp as a loop amp, could I use 0-21V rails on the opamp an still be able to tune HMC733 from 10-20GHz?

    The opamp I had in mind can output voltages within 0.2V of its rails.

    In other words, is 0.2V a low enough voltage to tune…

  • Converging time to target output frequency of HMC732 and HMC733

    Hi, 

    My customer has measured the converging time to target output frequency with HMC732 and HMC733.

    Their target convergence frequency is Fout +/- 4MHz withing 1us.

    Test results are in below. They made  two constant temperature module with HMC732 and…

  • Behaviour of HMC733 that seem to be out-of-specs

    Hallo everyone!

    We are having problems with HMC733 in our synthesizers. When the Vtune voltage is at a level corresponding to fundamental freq close to 18 GHz we observe that the VCO generates a particularly strong sub-harmonic signal at ca. 9 GHz This…

  • Phase noise data under vibration of HMC733, HMC508 & HMC764

    Hello,

    I received inquiry phase noise data under shock & vibration of HMC733LC4B, HMC508LP5 and HMC764LP6CE. Could you please send me the phase noise data under shock and vibration of HMC733LC4B, HMC508LP5 and HMCC764LP6CE? If you have some kind of data…

  • HMC739 VCO and HMC733 Mixer output is lower than expected

    I am using the HMC739 and setting the VTUNE to 2 is to get 24GHz.  I have the output of this going to the mixer.  The mixer is mixing in a signal and is send to an SMA connector that I have an antenna attached to.

    According to the HMC datasheet of the…
