APD design Suggestions
Hello,
I am planning to design a new photo detector based on an APD. We currently salvaged a very old APD off of a commercial system which seems to be hand made. It has CLC300A Comlinear wide band amplifier and a RCA C30950E APD. Attached is a picture of it.
The specs of the APD and Comlinear looks very good, but when we connect it and have a laser shooting the diode, the response is not as expected. I am also not clear why it has a 15KHz clock input on one of the input connectors.
Apart from this if you have any ideas on designing a good APD and wouldnt mind sharing it, that would be great. I know I have to define my specs before designing one, but just want to know if anyone has experience in designing these things.
Also I was not able to find any datasheet on AIE part. It looks like its a DC-DC converter since the bias voltage of the APD is ~600V, but again this is like 30 year old one.
thanks
