We are looking for a transimpedance amplifier with >700MHz bandwidth and low noise / high gain (10kOhm). The HMC799 would have appropriate specs but it is no available anymore (last time buy), PHY1095 the same, the ADN2880 has more BW than needed but could maybee work - but it is also not available anymore. The question is: Why are all the high speed transimpedance amplifiers gone? What would be the suggested alternative? The newer products (LTC656x, MAX4066x, MAX4065x, ...) are to slow.
Hi,
I am moving this thread to RF and Microwave community. Someone there should be able to assist you.
Thanks,

Hi,
Could you please check LTC6563? It can provide 600MHz bandwidth with 0.5pF photodiode capacitance

Depending on your photodiode capacitance, you may also try photodiode wizard and discrete op-amps to find a suitable solution

Thanks
We have a 2pF photodiode, the LTC6563 is in the 300MHz region with this input capacitance.
The Photodiode Circuit Design Wizard is only working in the 100 to 400M range, the LTC6269-10 is the best discrete solution ADI has to offer and unfortunately it is not quite able to reach this performance level.
I see the HMC799 is in stock, but not out of stock
The HMC7992 is in stock, which is a completely different IC, some distributors seem to have problems with this...
