Si Switchable Gain Detector Chapter 6: Specifications
Rev D, April 21, 2020 Page 7
Chapter 6 Specifications
All performance specifications are typical, performed at 25 °C ambient
temperature, and
assume a 50 Ω load, unless stated otherwise.
2
The PDA100A2
has a 50 Ω series terminator resistor (i.e. in series with amplifier output). This
forms a voltage divider with any load impedance (e.g. 50 Ω load divides signal in half).
3
Tested at 650 nm wavelength. For NIR wavelengths, the rise time of the photodiode element will
become slower which may limit the effective bandwidth of the amplified detector.
