Amplifier Researchc 500T2G8 TWT Amplifier : The Model 500T2G8 is a self-contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth and high gain are required. A reliable TWT provides a conservative 500 watts minimum at the amplifier output connector. Stated power specifications are at fundamental frequency. The amplifier’s front panel digital display shows forward and reflected output plus extensive system status information accessed through a series of menus via soft keys. Status indicators include power on, warm-up, standby, operate, faults, excess reflected power warning and remote. Standard features include a built-in IEEE-488 (GPIB) interface, 0dBm input, VSWR protection, gain control, RF output sample port, auto sleep, plus monitoring of TWT helix cur, cathode voltage, collector voltage, heater cur, heater voltage, baseplate temperature and cabinet temperature. Modular design of the power supply and RF components allow for easy access and repair. Use of a switching mode power supply results in significant weight reduction. Housed in a stylish contemporary cabinet, this unit is designed for benchtop use, but can be removed from the cabinet for rack mounting. The Model 500T2G8 provides readily available RF power for a variety of applications in Test and Measurement, (including EMC RF susceptibility testing), Industrial and University Research and Development, and Service applications. Functions and Specifications of the Amplifier Research 500TP2G8 TWT Amplifier Include: Power (fundamental), CW, @ Output Connector Nominal: 541 watts Minimum: 500 watts Linear @ 1 dB Compression: 125 watts minimum Flatness: ±8 dB maximum, equalized for ±5 dBmaximum at rated power  Frequency Response: 2.5 – 7.5 GHz instantaneously Input For Rated Output: 1.0 milliwatt maximum Gain (at maximum setting): 57 dB minimum Gain Adjustment (continuous range): 35 dB minimum Input Impedance: 50 ohms, VSWR 2.0:1 maximum Output Impedance: 50 ohms, VSWR 2.5:1 typical Mismatch Tolerance: Output power foldback protection atreflected power exceeding 100 watts.
