Overview

GT-E-DNC-7681 is a bench-top fundamental down-converter for noise-figure and receiver tests. Typical RF coverage is 76–81 GHz, converted to a typical 3–8 GHz IF using the integrated 73 GHz LO.

  1. Diagram block

    Integrated with LO.

Additional product details

The GT-E-DNC-7681 down-converter can be used for NF test and general receiver application.

Key Capabilities & Applications

Integrated conversion chain

The fixed internal LO removes the need for an external LO chain. RF-to-IF gain is 20 dB typical.

Waveguide and coaxial interfaces

A WR-12 RF port with UG-387/U flange and SMA female LO/IF ports connect the E-band converter to the bench.

Input and supply planning

RF input P1dB is +5 dBm typical; +13 dBm is the RF damage/absolute-maximum limit. An AC/DC converter is included for the +12 V bias supply.

Common applications

  • Noise figure test
  • 5G communication
  • ROF (RF over fiber)
  • Radar system
  • RCS test
  • Bench-top labs test
