- Abstract:
- Two aLIGO LSC style RFPDs are being prepared for use in the Squeezing upgrade. The CLF operating frequency is 6.25MHz, and the OPO operating frequency is 80MHz. This note captures the basic operating characteristics of each new design.

- Notes and Changes:
- It should be noted that the results for the 80MHz RFPD were calculated based on an InGaAs photodiode, whereas the actual diode used will be a silicon photodiode (Excelitas FFD-100H) having different impedance characteristics at 80MHz. The differences in response will likely be small.
