Antenna Suite Targets HIRF Testing Applications
A suite of three high-gain, high-power microwave horn antennas from AR RF Microwave are intended for use in DO 160 HIRF (high intensity radiated frequency) testing. These antennas provide even more options for varying test conditions. The AT4444 provides 2 to 4 GHz/ 1000 watts CW / 17-kw pulse input power while the AT4446 provides 4 to 6 GH / 800 watts CW /15-kW pulse power. … [Read more...]
Empower RF Helps Prepare Broadcasters for February 2009 Analog TV Cutoff
FCC orders to cease analog television broadcasts have left the networks scrambling to ensure complete airwave coverage by the February 2009 cutoff date. The new broadcast type—digital TV, or DTV—promises to bring vastly superior picture, sound and channel selection to the airwaves free of charge. Companies like Empower RF have stepped up efforts to develop miniaturized DTV … [Read more...]
Antenna Mast Crafted for EMI/EMC Testing
The AM-400 from Com-Power Corporation is an antenna mast well suited to making EMC measurements in an OATS (open air test site) or in test chambers. The height of the antenna can be varied from one to four meters during measurement as required by commercial EMC specifications. The mast is constructed using fiberglass tubes and grating material. These were chosen because they … [Read more...]

High End Log Periodic Broadband EMC Antenna for 380 MHz to 18 GHz
The HyperLOG™ Series 3000 from German EMC firm Aaronia AG is based on an ultra-thin, gold-plated, high tech TEFLON substrate. This innovative construction makes an extended frequency range possible. This extended frequency range now goes down to 389 MHz allowing use in the increasingly important TETRA band (380 MHz +). Additionally, the frequency range up to 18 GHz allows … [Read more...]
Portable, Folding Biconical Antenna Performs Site Attenuation Measurements
The SAS-542 Folding Biconical Antenna from A.H. Systems was the first EMC antenna designed for portable compliance testing applications. Product features include a frequency range of 20 MHz to 330 MHz, maximum continuous power of 1 watt, impedance of 50 Ω, and a maximum radiated field of 2 V/m. These antennas are individually calibrated (1-, 3- and 10-meter calibration … [Read more...]
Broadband EMC Test Antenna Target Emissions and Immunity Testing
The JB Series antennas from Sunol Sciences Corporation are compact instruments for EMC emissions and immunity testing. The antennas’ broadband characteristics allow operation over a wide frequency range—a necessity in automated test environments. The antenna boom is made from a custom aluminum extrusion that reduces the number of parts at the nose, resulting in stable feedback … [Read more...]
