With the introduction of the ART1K6FH and ART1K9FH models, Ampleon extends its support for next-generation high-power industrial, scientific, and medical (ISM) designs with its newest breakthrough RF power transistors, powered by a 50 to 55 V supply. These additions complement an already leading ART portfolio, offering a full series of high breakdown voltage and exceptionally rugged Solid State Power Amplifier (SSPA) options ranging from 700 W, 1400 W, 1600 W, 1700 W to 1900 W. Ampleon's new line of 50 V ART transistors deliver a higher breakdown voltage and better efficiency levels when compared to the predecessor 50 V XR transistor family and come in a variety of air-cavity ceramic and over-mold plastic packages with long-term longevity commitments. The ART1K6x and ART1K9x transistors are designed in push-pull air cavity ceramic (ACC) and over-mold plastic (OMP) packages, ensuring up to 1900 watt Class AB performance across the frequency range from 1 MHz to 400 MHz.
