ADL5561 , Ultralow Distortion RF/IF Differential Amplifier

Hello, I am using ADL5561 Low Noise Amplifier Evaluation Board of Analog Devices. I tested the board for Gain at different frequencies. It was providing a gain of 12 dB (Gain adjustment done referring the datasheet to obtain a Gain of 15.5 dB). For retesting the board I switched on the signal generator and spectrum analyzer but the power supply was switched off by mistake.  At that time the signal generator input was -100 dBm at 10 MHz frequency. The amplifier is now acting as an attenuator providing an attenuation of 20dB. Can you please help in debugging the problem.

Regards,
