Hi,

We are using the AD8330 in one the board, when i am checking the Gain Amplification with different input frequencies, i found that lower frequencies Output is not coming.

Here when i apply the input frequency around 300KHz, output is amplified.

When i apply the 20KHz input, Some times Amplified Output, but, most of the time, No Output ta all.

WHen probe the Device Input pins, proper input is applied, and VDBS voltage is constant and no change from when High Frequency test done.

 

Here only, Input frequency is reduced.

 

Is ther any problem?. Has device is verfied from DC to 150MHz, as mentioned?.

What is the minimum frequency can apply for working?.

 

I had attched the AD8830 schematics.

 

 

Thanks

Reddy
