AR offers video tour of 10-kHz to 40-GHz system for MIL-STD-464 testing

Dec. 22, 2016

AR RF/Microwave Instrumentation offers a range of turnkey systems for testing in accordance with various standards including MIL-STD-461, MIL-STD-464, and DO-160 as well as automotive, HIRF, and IEC standards.

AR currently offers standard and custom system solutions. The company has developed a video in which applications engineer Flynn Lawrence discusses AR’s turnkey system design and development.

He offers as an example a system designed for MIL-STD-464 testing. The system spans 10 kHz to 40 GHz and provides up to 500-V/m field strength.

Components include an amplifier providing 10,000-W rated CW power from 10 kHz to 225 MHz plus a 2,000-W amplifier spanning 80 MHz to 1 GHz.

Inside a shielded cabinet is the part of the system designed to span from 1 GHz to 18 GHz. A system interlock connected to a power-distribution unit provides filtered, breakered power to all the components within the system. A power meter measures all forward and reflected power from each of the amplifiers. A signal generator provides all CW and modulated signals to all the amplifiers, while a system controller routs all RF. Amplifiers include a 700-W unit operating from 1 GHz to 4 GHz, a TWT amplifier providing 500 W from 2.5 to 7.5 GHz, and finally another TWT amplifier providing 500 W from 7.5 GHz to 18 GHz.

The system is completely enclosed in a shielded rack designed to be placed in the shielded test chamber to minimize system losses between amplifiers and antennas, he explains.

The last part of the complete system includes a 40-W TWT amplifier providing instantaneous power from 18 to 26.5 GHz and another TWT amplifier providing 40 W of rated power from 26.5 to 40 GHz.
