2 Measured with a specified bias voltage of 1.8 V.
3 Low battery voltage will result in slower rise times and decreased bandwidth.
4 For a 50 Ω Load
5
Measured with a 1 M Ω Load
6
Measured from the active area to the start of the threads on the housing body. The detector
active area surface is flush with the front of the housing body.
7
Assumes the battery voltage drops below 9.6 V. The reverse protection diode generates a 0.6
V drop.
