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 PDA10A2 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
When long-term UV light is applied, the product specifications may degrade. For example, the
product’s UV response may decrease and the dark current may increase. The degree to which
the specifications may degrade is based upon factors such as the irradiation level, intensity, and
usage time.
