Double Ridge Active Horn Antenna

The AHA-840 Active Horn Antenna operates from 18 GHz to 40 GHz for EMI and EMC testing.

• Covers 18 GHz to 40 GHz frequency band; suitable for modern high-frequency EMC test standards.
• It features a built-in low-noise preamplifier for enhanced signal sensitivity.
• High preamplifier gain of 37–43 dB; ensures enhanced signal reception across all test scenarios
• Low noise figure below 6 dB; maximizes signal-to-noise ratio in low-level signal environments
• The antenna includes a double ridged waveguide design with precise impedance matching.
• It is individually calibrated per ANSI C63.5 with NIST traceability.
• Full system calibration reduces measurement uncertainty.
• This antenna supports both radiated emissions and immunity testing.
• External connections allow filters and attenuators to be added.
• The antenna factor remains flat across its broadband frequency range.
• It can generate up to 1100 V/m @ 1 meter with 200W input for immunity tests.
• Ideal for high-frequency EMC applications with flexible setup options.
• Lightweight and compact design; weighs only 1.5 lbs (0.68 kg), enabling portable and flexible deployment.
• Precision waveguide-to-coax adapter included; supports optimal VSWR (1.4:1 avg) for improved test integrity.
