SIP



ULTRA SMALL PREAMPLIFIER

Description

SIP is the ultra small transimpedance, AC or DC coupled preamplifier. It is dedicated for OEM applications and requires external heat sink (see Recommended Accessories).
SIP is designed for operation with either biased or non-biased and either cooled or uncooled detectors.
  • Very small size
  • High signal-to-noise ratio
  • Bandwidth up to 250 MHz
  • Dedicated for operation with 2-, 3- and 4-stage TE cooled or uncooled detectors
  • Biased and non-biased detector compatible
  • Adjustable gain (for bandwidth up to 100 MHz)
  • Fully protected against exceeding supply voltage and reversing power supply polarity
  • Custom modifications upon request
  • Additional accessories available

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
4) Measured with equivalent resistor at the input instead of the detector. It's to avoid the environmental thermal radiation's impact
