3115-PB Double-ridged Waveguide Horn with Pre-amplifier
Key Features
- 1 GHz to 18 GHz Frequency Range
- Designed for MIL-STD 461
- Fitted with Pre-Amplifier for Increased Sensitivity
- Pre-Amplifier and Antenna Calibrated as a Single Unit
- Extremely Low AF Flexible Mounting
- Not intended for RSE Testing of Intentional Radiators
ETS-Lindgren's Model 3115-PB is our popular Model 3115 Double-Ridged Waveguide Horn Antenna, fitted with an updated pre-amplifier package and calibrated as a single unit. In this configuration, any possible mismatches between antenna and pre-amplifier are taken into account in the antenna factor (AF) which is provided with this unit. Please note, the 3115-PB is not intended for RSE testing of intentional radiators.
Product 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.
Designed for MIL-STD-461
The 3115 Horn Antenna (without pre-amplifier) is identical to the antenna described in MIL-STD-461 RE102, for emissions testing above 1 GHz.
Fitted Amplifier
The pre-amplifier has a frequency range of 1 GHz to 18 GHz and a typical gain of 28 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 pre-amplifier are an input and output VSWR of 2: 1 maximum.
Calibrated as Single Unit
The 3115-PB is calibrated as a single unit, so uncertainty values are reduced.
