Product Overview

RENT AR 500T7z5G18 (call for availability)

The Amplifier Research (AR) 500T7z5G18 is a self contained, forced air cooled, broadband traveling wave tube (TWT) microwave amplifier designed for applications where instantaneous bandwidth, reduced harmonics and high gain are required. A reliable TWT subsystem provides a conservative 500 watts minimum at the amplifier output connector. Stated power specifications are at fundamental frequency.

The AR 500T7z5G18 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, 0 dBm input, VSWR protection, gain control, RF output sample port, plus monitoring of TWT helix current, cathode voltage, collector voltage, heater current, heater voltage, baseplate temperature and cabinet temperature.

The modular design of the AR 500T7z5G18 Amplifier's power supply and RF components allow for easy access and repair. Use of a switching mode power supply results in significant weight reduction.

The rated power is developed by efficiently power combining the outputs from two 300 watts (nominal) microwave tubes that are factory matched in gain and phase to offer moderate harmonic levels without added filters.

Housed in a stylish contemporary cabinet, the AR 500T7z5G18 Amplifier is designed for bench top use, but can be removed from cabinet for rack mounting. The AR 500T7z5G18 Amplifier 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.

Features and specifications of the AR 500T7z5G18 Amplifier include:

  • Power (fundamental), CW, @ Output Connector:
    • Nominal: 550 watts
    • Minimum: 500 watts
    • Linear @ 1 dB Compression: 125 watts minimum
  • Flatness: ±11 dB maximum, equalized for ±3 dB maximum at rated power
  • Frequency Response: 7.5 - 18 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
