I am currently trying to use he HMC561LP3 eval board. I am currently driving it with an input on the order of 3.5dBm at 5GHz with a supply voltage of ~5V (4.9V). I set Vgg to around -1.5V giving a and Idd of 98mA. Under these circumstances the device…
The datasheet states to adjust Vgg between -2.0 and -1.2V to achieve Idd1 + Idd2 = 98 mA, i want to adjust VGG with a voltage divider so i need to know the Vgg input current to compensate for the voltage drop across my divider.
Thank you MRichardson.
I'm still not able to find the footprints for the HMC561LP3. Do you have any clues?
Our customer need detailed layout guideline and PCB stack up guideline for the following devices.
Are Gerber files available for the evaluation board?
I have read many questions and answers about the HMC637ALP5E and various application documents.
And there are three questions:
1）The same type amplifier e.g. HMC797APM5E provides a relationship between Idd and Vgg1(Representative of a Typical D…
