ETS-Lindgren’s Model 3117-PA Double-Ridged
Waveguide Horn Antenna with Pre-Amplifier
ETS-LINDGREN’S MODEL 3117-PA
is a special version of our popular
Model 3117 Double-Ridged Wave-
guide Horn Antenna, tted with a
pre-amplier package and calibrated as a single unit. By doing this,
any possible mismatches between
antenna and pre-amplier are
taken into account in the antenna
factor (AF), which is provided
with this unit. The antenna is ideal
as a receive antenna for emissions
testing above 1 GHz.
FEATURES
Frequency Range
This antenna covers the 1 GHz to
18 GHz range making it ideal as a
receive antenna for any emissions
testing above 1 GHz.
Maintains Single Lobe Radiation
Like the Model 3117, the Model
3117-PA maintains a single main
lobe pattern in the direction of the
horn axis over its frequency range.
This characteristic is essential for
even distribution of electromagnetic
energy on a target surface, and
accurate measurement of gain
and emissions. The model 3117’s
unique design suppresses the
propagation of high order modes.
The result is an antenna with a welldened single lobe radiation pattern
that outperforms other antennas in
its class.
Fitted Amplifier
The pre-amplier attached to the
antenna has a frequency range of
1 GHz to 18 GHz and a typical
gain of 48 dB. The gain atness
across the range is ± 2.5 dB. The
pre-amplier has a maximum noise
gure of 4 dB maximum with the
typical noise gure being 3 dB. The
power output is +17 dB minimum at
the 1 dB point. The input and output
characteristics of the preamplier
are an Input and output VSWR of
2:1 maximum.
Low Antenna Factor
The result of matching the Model
3117 with the pre-amplier is
an antenna that is calibrated as a
system and it provides an extremely
low AF that is less than -2 dB (1/m)
for the entire frequency range.
Flexible Mounting
The Model 3117-PA includes both
a 1/4 20 thread classic mount and a
rear “stinger” mount.
