gRX-LAN

gRX-LAN Receiver


The gRX-LAN Advantage (Hensoldt, former GRW)

The GRXLAN family of SDR’s (software definable receivers) provides a cost effective solution where single or multiple receiver channels are required in a communication EW environment. The receivers provide base band I/Q outputs, which then may be manipulated to derive spectral information including demodulation for listening purposes.

High dynamic range circuitry, with Digital Signal Processing and sophisticated host man-machine interface graphics combine in a cutting edge SDR solution for modern HF & V/UHF ESM monitoring requirements.
LAN interface offers stand alone and advance system applications.

Features

  • Combined H/V/UHF model (LU up to 3.6 GHz)
  • Tabletop 1 to 2 channels
  • Optional frequency extender to 9 GHz
  • Suitable for fixed, mobile, airborne and naval applications
  • Direct sampling (no mixers) employed in HF section
  • Excellent Phase Noise especially in the HF section - limited only by clock’s phase noise

gRX-LAN

Digital Signal pre-processing for optimum adaptation to receiving and signal conditions.

Excellent large signal behaviour i.e. low levels of intermodulation and crossmodulation
