ETS-LINDGREN’S MODEL 3117-PA

is a special version of our popular

Model 3117 Double-Ridged Wave-

guide Horn Antenna, fitted with a

pre-amplifier package and calibrat-

ed as a single unit. By doing this,

any possible mismatches between

antenna and pre-amplifier 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 well-

defined single lobe radiation pattern

that outperforms other antennas in

its class.

Fitted Amplifier

The pre-amplifier attached to the

antenna has a frequency range of

1 GHz to 18 GHz and a typical

gain of 48 dB. The gain flatness

across the range is ± 2.5 dB. The

pre-amplifier has a maximum noise

figure of 4 dB maximum with the

typical noise figure being 3 dB. The

power output is +17 dB minimum at

the 1 dB point. The input and output

characteristics of the preamplifier

are an Input and output VSWR of

2:1 maximum.

Low Antenna Factor

The result of matching the Model

3117 with the pre-amplifier 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.
