FIP



FAST PREAMPLIFIER

Description

FIP is the high speed transimpedance, AC coupled preamplifier. It is dedicated for high speed infrared measurements.
FIP preamplifier is designed for operation with either biased or nonbiased TE cooled detectors.
  • Compact size
  • Wide bandwidth up to 1 GHz
  • Precise I-V conversion
  • Detector biasing possibility up to +800 mV
  • Low current noise
  • Co-operation with high resistance detectors
  • Effective cooling up to 4-stage TE coolers

1) The preamplifier noise may significantly reduce the system perfomance in some situations.
    This happens for large capacitance detectors operating at high frequencies
2) fo - noise measurement frequency
3) RL - load resistance
