Introducing the Amplifier Research 200T18G26Z5A TWT Microwave Amplifier
The Amplifier Research 200T18G26Z5A is a state-of-the-art, self-contained broadband traveling wave tube (TWT) microwave amplifier designed for high-performance environments requiring wide instantaneous bandwidth, robust gain, and moderate power output. This advanced model delivers a reliable minimum power of 200 watts at the amplifier output connector, tailored for applications demanding precision and reliability.
Designed for versatility, the amplifier's front panel features a user-friendly digital display, showcasing critical readings including forward and reflected output in addition to comprehensive system status metrics. Gaining information is effortless through an intuitive series of menu-driven soft keys that report on vital indicators such as power on, warm-up status, standby, operational status, fault detection, reflections, and remote operation.
Key Features:
- Built-in IEEE-488 (GPIB) interface for seamless integration
- Robust VSWR protection for increased operational safety
- Continuous gain control with a range of at least 35 dB
- RF output sampling ports to facilitate efficient monitoring
- Comprehensive thermal monitoring including TWT helix current, cathode voltage, collector voltage, and cabinet temperature
The modular design of the power supply and RF components allows for straightforward access and maintenance, enhancing user efficiency. By leveraging a switching mode power supply, the amplifier achieves a significant reduction in weight without compromising performance. Its rated output power is produced through the power combining of two factory-matched microwave tubes, each delivering nominally 150 watts.
Sleekly housed in a modern cabinet, the 200T18G26Z5A is engineered for benchtop applications but can also be easily modified for rack mounting. This versatile amplifier supports an array of applications in Test and Measurement, EMC RF susceptibility testing, Industrial and University research and development, and various Service applications. With moderate harmonic content, it paves the way for precise and effective experimentation.
