HMC6590 Gain

Good afternoon,


I am using the HMC6590 transimpedance amplifier to amplify the signal from a high speed photodiode. However, the measured gain is approximately 10x less than expected and the output appears to be oscillating at around 1GHz.


Can anyone help as to what the cause of the oscillations and lower gain could be?
