Introducing the Amplifier Research 200T8G18 TWT Amplifier
The Amplifier Research 200T8G18 is an advanced, self-contained broadband traveling wave tube (TWT) microwave amplifier that excels in applications demanding instantaneous bandwidth and exceptional gain. With a robust design, this amplifier delivers a reliable output of 200 watts minimum at the output flange, made possible by its powerful 250 watt TWT, ensuring consistent performance at the fundamental frequency.
Key Features:
- Broadband Performance: Frequency response spans an impressive range of 7.5-18 GHz instantaneously.
- Power Specifications:
- Minimum output: 200 watts
- Linear @ 1dB Compression: 50 watts minimum
- Advanced Display: The front panel features a digital display that provides critical data on forward and reflected output, along with extensive system status information accessed via intuitive soft keys.
- Comprehensive System Monitoring: Includes monitoring for TWT helix current, cathode voltage, collector voltage, heater current and voltage, baseplate and cabinet temperatures, and excess reflected power warning.
- Versatile Input and Output:
- Input for rated output: 1.0 milliwatt maximum.
- Output impedance: 50 ohms with VSWR 2.5:1 typical.
- Input impedance: 50 ohms with VSWR 2.0:1 maximum.
Superior Design and Build:
Engineered with modularity in mind, the power supply and RF components allow for easy access and repair, making maintenance a breeze. The use of a switching mode power supply not only enhances reliability but also significantly reduces the overall weight of the unit. The contemporary cabinet design accommodates benchtop usage while allowing for easy removal for rack mounting when needed.
Modulation and Tolerance:
- Modulation Capability: Capable of faithfully reproducing AM, FM, or pulse modulation on the input signal, with AM peak envelope power limited to specified power.
- Mismatch Tolerance: Output power features fold back protection when reflected power exceeds 40 watts, allowing operation without damage or oscillation despite variations in source and load impedance.
Impressive Noise and Distortion Characteristics:
- Noise Power Density:
- Pulse on: -70 dBm/Hz (maximum), -72 dBm/Hz (typical)
- Pulse off: -140 dBm/Hz (typical)
- Harmonic Distortion:
- Below 10 GHz: < -5 dBc max, -8 dBc typ.
- 10-12 GHz: < -8 dBc max, -12 dBc typ.
- Above 12 GHz: < -20 dBc max, -30 dBc typ.
Operational Power and Cooling:
- Primary Power Requirement: 190-260 VAC, 50/60 Hz single phase, with a maximum of 2.0 KVA.
- Cooling System: Equipped with forced air cooling via self-contained fans, ensuring optimal thermal performance with air entry and exit at the rear.
