Amplifier Research 1000T2G8B TWT Amplifier (Call for Availability)
The Amplifier Research 1000T2G8B is an advanced, self-contained TWT microwave amplifier optimized for applications demanding broad instantaneous bandwidth, elevated gain, and robust power output. Built to excel in high-performance environments, this amplifier delivers a reliable minimum output power of 1000 watts across a significant portion of its frequency range. The device is engineered for precision, with power specifications noted at its fundamental frequency.
Featuring a user-friendly front panel digital display, the 1000T2G8B provides real-time monitoring of both forward and reflected output, along with extensive system status information accessible through an intuitive menu system. Key status indicators include power on, warm-up, standby, operate, fault warnings, excess reflected power alert, and remote operation capabilities.
The amplifier is equipped with a comprehensive suite of standard features, including:
- Built-in IEEE-488 (GPIB) interface
- Gain control with extensive monitoring capabilities for TWT helix current, cathode voltage, collector voltage, heater current, heater voltage, baseplate temperature, and cabinet temperature.
Designed with a modular architecture, the power supply and RF components allow for straightforward access and maintenance. The innovative switching mode power supply contributes to a considerable weight reduction. The efficient power output is achieved by combining the outputs from two factory-matched microwave tubes, each rated at 535 watts, ensuring moderate harmonic levels without the necessity for additional filtering.
