Traveling wave tube amplifiers

January 17, 2011
AR’s traveling wave tube amplifiers cover 0.8 to 45 GHz, CW power to 2700 watts and pulse goes to 16,000 watts. These amps provide coverage for a wider range of high-power microwave and EMC test application than any other brand of microwave amplifier. Plus they’re rich with features that make testing quicker, easier and more accurate.

We also offer a line of hybrid amplifiers that marry solid-state amplifiers and TWT power in a single unit. These models offer combinations of power and frequency carved out expressly for Telcordia (which requires suppressed harmonics) and EMC microwave applications. Each unit is designed for the 0.8 – 18 GHz frequency range and they provide 10, 20, 35 and 50 watts of CW power. Hybrids provide a cost-effective solution to frequency coverage problems by combining solid-state and TWT elements. They also eliminate the need for cable switching required when two amplifiers are used – a painstaking procedure that can lead to system errors and repeatability problems.
