Description
Overview
The Amplifier Research 250T8G18 is a self-contained, forced air-cooled broadband traveling wave tube (TWT) microwave amplifier designed for applications requiring instantaneous bandwidth and high gain. The amplifier delivers a minimum of 250 watts of RF power and provides conservative specifications at the fundamental frequency. A modular design allows for easy access and maintenance, while a switching mode power supply reduces overall weight.
