Getting started with ADL5511-EVALZ evaluation board

Hi,

 

I am trying to use a "ADL5511-EVALZ" evaluation board for a envelop detection application.

 

I've tried testing the board by powering it up using a +5V supply and applying a 2 GHz signal switched at 1 kHz to the RF IN port.

The output at the VENV was tested using an oscilloscope.

 

However the board any response from the outputs. (VENV / VRMS) and both of them remained close to zero regardless of the input signal.

I've also tried applying a continuous wave signal without any envelop but still the VENV was close to zero.

 

From what I understood from the datasheet VENV should vary around 1.1 V reference voltage. However I was not able to observe this or get the board working. Is there any additional steps that need to be taken to operate this board?

 

Thanks in advance,

Uditha
