ADL5511 EVALZ Getting Started

Hi,

 

I just purchased an ADL5511 EVALZ. I can't get any envelope output except for a DC voltage.

Here are what I did:

 

1. Connect VPOS to 5V, GND to ground

2. RFIN is a 20MHz LTE-like signal carried at ~2.6GHz.

3. Switch is at "on"

 

Actually, I also tried other input signals at different frequencies, or even no input, the output from VENV is nothing but a DC voltage ~1V.

 

Can anyone tell me what did I do wrong, or the evaluation board is not working?

 

Thanks
