Models FTA820A-P
8-Channel Fast Amplifiers

Multi-channel amplifier for fast analog signals from photomultipliers, electron multipliers, photodiodes, microchannel plates, and silicon charged-particle detectors

<20 mV rms equivalent input noise

<1 ns rise time

Gain: 200

Output drives -5 V into 50 W

Eight separate and identical amplifiers in a single-width NIM module

General
These amplifiers are high-performance, wide-bandwidth units designed for boosting very fast linear signals from photomultipliers, electron multipliers, silicon charged-particle detectors, and other detectors used in fast-timing applications. The rise time is <1 ns with a 5 V output, enabling excellent timing resolution.

The Model FT820A-P provides eight separate and identical amplifiers in a single-width NIM module. Each amplifier section has a voltage gain of x200 (non-inverting), with LEMO type 00C50 connectors being used for all signal connections.
