I had purchased the following component from Analog Devices : HMC600LP4 and fabricated the evaluation board according to the layout provided by Analog Devices. When we tested for its functioning, the output value was near to supply voltage value (Vcc) for all the input signal power ( the signal power was varied from -60 dbm to 10 dbm ) at the frequency of 1.3 GHz. Additionally, the response was flat.
It would be of great help to me if you could let me know the reason for getting such an output in addition to any suggestions to get the required output ?
Also I provided supply and ground connections using wires as shown in the figure attached below. Is this the way to be done?
