Broadband Power Amplifier 100 Watts for Conducted Immunity
- ▸ ACS-250-100W broadband RF power amplifier, 150 kHz–250 MHz — a 100-watt RF amplifier built for IEC 61000-4-6 conducted RF immunity testing and a wide range of EMC applications.
- ▸ 100 W rated output for rigorous immunity testing — delivers a powerful 100 W into a 2:1 VSWR load, providing ample energy for demanding conducted immunity test scenarios.
- ▸ 50 dB gain with no compression up to 100 W — maintains clean, undistorted output across the full band, with only a 0 dBm input required for rated output.
- ▸ Extended 250 MHz upper frequency — the wider 150 kHz–250 MHz range covers more EMC test applications than 230 MHz-class amplifiers.
- ▸ Automatic safety shutoff for equipment protection — shutdown activates if load VSWR exceeds 7, with a 140 W safety threshold, protecting the amplifier and connected accessories.
- ▸ Versatile AM, FM, and pulse modulation support — accepts multiple input modulation formats for flexible integration with signal generators and test systems.
- ▸ Front-panel LCD and USB automation interface — the LCD shows current, temperature, RF power, VSWR, and gain; USB connectivity enables automated test integration.
- ▸ 4U rack-mount chassis with forced-air cooling and three-year warranty — the 19-inch rackmount design maintains safe operating temperature during extended use, backed by a 3-year warranty.
