General Specifications
VivaTech THz Noise Figure Downconverters are designed to extend calibrated noise figure and gain measurements into millimeter wave frequency bands. The THZBDC-XXFBE series covers 40 to 170 GHz across standard waveguide bands and is intended for use with compatible noise figure meters and spectrum analyzers.
These downconverter systems support swept frequency measurements and are supplied with a compatible solid-state noise source. Typical system characteristics include 30 dB overall gain, 10 to 15 dB typical noise figure, SMA-F LO/IF connectors, 10 MHz to 3 GHz IF output, and +12 V DC power operation.
Noise Figure Downconverters
VivaTech THz offers noise figure downconverters for extending calibrated noise figure and gain measurements into millimeter wave frequency bands. These products are useful for receiver testing, amplifier characterization, and measurement setups where standard coaxial noise figure equipment must be extended into waveguide bands. The table below lists representative THZBDC-XXFBE downconverter models with frequency range, LO input frequency, typical noise source ENR, test range, and waveguide interface.
