[Hackrf-dev] Mixer Conversion Loss

[Ibrahim Basaran]

Hi, 
We have came across a new problem with HackRF One. Starting from 2700MHz the signal strength gradually decreases. 
Here are two tests for 2500MHz and 3000MHz, http://i.hizliresim.com/YjPBJ6.png , the signal strength from signal generator are the same for both tests, however, 
hacRF sees weaker signal for 3000MHz. If you input 5000MHz it is even more attenuated. 

We have checked high pass filter output and both signals had similar strength but after mixer 3000MHz signal have attenuated a lot. 

What do you think is the problem? 
Anybody with the same problem.
