The
NC3400 Series
coaxial noise sources are an
excellent choice for applications requiring high
ENR and immunity to large incident RF power,
such as ATE, radiometer, and radar systems.
The calibration accuracy and flatness
of the
NC3400 Series
noise
sources are enhanced by
their low VSWR. The
built-in isolator provides
almost constant output
impedance as the
noise source bias is
switched on and off.
The isolator also protects the
noise diode from incident RF power
(consult factory for higher-power units).
An SMA female connector is standard for
the RF output and a BNC female connector is
standard for the bias input. Other connectors
are available as options.
Applications:
Radar systems
High NF device measurements
Automated test equipment (ATE)

* Flatness for units optimized for bandwidths less than 10 percent of the
center frequency is less than 0.25 dB. Improved VSWR may also be obtained
for units with reduced bandwidth.
** VSWR for models with N connector is 1.35:1 up to 12 GHz. N connectors
are not recommended for frequencies above 12 GHz.
