• ### 关于HMC1030的有关问题，求大神解答一下！谢谢！

PDF

我的实验目的是，利用HMC1031实现频率跟踪（即倍频为1），其中参考频率（EXT_REF端输入）和VCO频率（EXT_VCO端输入）都在0.1-10M以内，符合参考手册上的频率范围要求。

在初步实验中，我们给定两个频率有略微差别的标准方波（都在2.7M左右）分别接入EXT_REFEXT_VOC端，在VTUNE端采集到的信号如下图（附件中示波器上面的黄色波浪线…

• ### HMC1030

Could you please provide the gerber files for the evaluation board EVAL01-HMC1030LP5E for layout guidance? Thanks.

Hi David,

Yes, HMC1030 probably would be better for this application, compared to AD8302, for est accuracy.

• ### RE: ADL5519 output noise

Greetings Mike,

It was very fortunate that we were able to find the ADL5513 output NSD plots that extended to lower frequency. I've looked but have not been able to locate such data for ADL5519.

• ### Calculating VSWR using dual Linear-in-dB RMS Detecto

Question: If I’m using a device such as AD8364 or HMC1030 to measure VSWR, how do I actually get from output voltage (or ADC code) to VSWR?

Answer: The short answer is that the return loss in dB is proportional to the differential voltage that…

• ### Power detection for Baseband I/Q signal

Hi everyone,

I want to use HMC1030 to measure the power of baseband I and Q signal in order to calculate the power of the signal before demodulation. Does the HMC1030 can measure the power for baseband I/Q signal?

If there is other option, I really…

• ### RE: 07-26-17 Any application note for connecting 55dBm signal to ADL5920?

On behalf of Eamon Nash.

Unfortunately, this will not work. The ADL5920’s max input power is hardwired at +30 dBm. I think that there may be scope to increase this to +33 dBm but definitely not to 55 dB. I think that your only option is to use conventional…
