I'm trying to build a trans impedance amplifier for the photo-diode (homodyne detector) for frequencies above 200 MHz. I used a diagram from the HMC799 Data sheet. But amplifier generates a sine signal frequency of about 640 MHz. Could you tell me where I made the mistake?

I use to test FCI InGaAs 120L photo-diode in the future I plan to use a Hamamatsu G6854-01
