First article of the CTN beat PD |
|
|
Made the first article of the 25MHz resonant PD for CTN experiment.
Performance:
Resonant frequency f_res = 26.0MHz
Transimpedance R_res = 2.3kOhm
Input referred curent noise = 10pA/rtHz
Shot noise intercept current = 0.29mA
Remarks:
MAX4107 at G=10 gives a gain peaking at 260MHz. It is not tamed as the dark spectrum shows the peak does not have significant RMS.
But this might cause a trouble later. We can consider to replace the opamp with ones suggested by Rana. Rana bought "THS4271" to give it a try. |
