The Amplifier Research 15T4G18A is a self-contained, forced-air cooled, broadband TWT microwave amplifier, designed for applications requiring low harmonic content in selectable sub-bands with wide bandwidth, high gain, and reliable output power. It delivers a conservative 15W minimum at the output, 10W in low harmonic mode, with up to 40W nominal power. The front panel provides a digital display for forward/reflected power and full system status. Built-in IEEE-488 (GPIB), VSWR protection, gain control, and monitoring functions ensure safe operation and easy diagnostics. Modular design and switching power supply provide lighter weight and simplified serviceability.
Ideal for EMC RF susceptibility testing, research and development, and industrial or academic use, the 15T4G18A amplifier offers flexible frequency response from 4.2–18 GHz and faithful modulation reproduction, making it highly versatile for advanced RF test environments.
