The 5700TP12G18 from AR RF/Microwave Instrumentation is a self-contained, broadband traveling wave tube (TWT) microwave amplifier that operates from 12 to 18 GHz. It delivers an output power of more than 5700 W with a gain of over 67 dB and has a VSWR of less than 2.5:1. The rated power is developed by efficiently power combining the outputs from two 3400 watts (nominal) pulse TWTs that are factory matched in gain and phase. It has a harmonic distortion of less than -15 dBc and a maximum noise power density of -55 dBm/Hz. This amplifier system is designed for pulse applications at low to moderate duty factors where instantaneous bandwidth and high gain are required.
The amplifier’s front panel digital display shows forward and reflected output along with 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 ports, auto sleep and monitoring of TWT helix current, cathode voltage, collector voltage, heater current, heater voltage, baseplate temperature and cabinet temperature.
The 5700TP12G18 is available in a module housed in a contemporary cabinet measuring 50.3 x 43.0 x 84.0 cm with N-type (female) input connector and WR-62 output waveguide flange. It is suitable for test and measurement, (including EMC RF susceptibility testing), industrial and academic R&D, and Service applications.
