AmplifiersPRO-LNAHP-4-3-2

Low-noise Preamplifier for the 4 m, 3 m and 2 m bands 68 - 240 MHz

Description

  • Miniature high-dynamic range low-noise preamplifier for the 4 m LMR band, the FM radio band, the VHF air band, the 2 m LMR band and the DAB radio band.
  • Covers 68  – 240 MHz.
  • For use where additional preamplification may be required:
    • In receiver systems to ensure low system noise figure
    • As buffer amplifier in RF signal distribution systems
    • As buffer amplifier to compensate high cable loss
    • As preamplifier for measuring instruments
  • Adjustable gain.
  • Very low noise figure ensures best possible S/N ratio of weak RF signals.
  • Excellent large signal behaviour ensures handling of strong RF signals with very low level of IM and harmonic distortion.
  • Low power consumption.
  • Models for 12 VDC or 24 VDC supply voltage available (please see ordering designations).
  • DC supply on solder terminal.
  • RF connectors: N-female on input and output ports (other types on request).
  • Low weight.
  • Wide temperature range.
  • Sturdy aluminium box.
  • PRO-LNAHP-4-3-2 is coated with black vinyl to prevent corrosion.
