ADL5519 for pulse measurement

I am in the process of finalising an RF detector using the ADL5519 development
board and I would appreciate some advice as I am unable to detect RF pulses
shorter than 1us.

 As the datasheet details a pulse response of 6ns I was expecting the ADL5519
to be able to respond to these pulses, but it may be the case of the
development board limiting the pulse response hence the question.

 It is my intention to dispense with the development board after the design has
been finalised but I will not be able to progress to this stage until I can
show that the final device will see these narrow pulses.

 

CLPA and CLPB have a 1000 pF capacitor installed by default. These capacitors
need to be removed for pulse measurement operation.
