About

National Physical Laboratory awarded a contract to Amplifier Research for the supply of a 10 kHz to 250 MHz 500 Watt amplifier, valued at £49,819.

The equipment is required for the calibration of radiation hazard probes and field strength sensors, replacing an existing Amplifier Research 500A100 amplifier that is over 25 years old and has reduced output.

The new amplifier's wider frequency range will eliminate the need to move another amplifier from a different calibration area for measurements from 100 to 250 MHz.

Reflective low pass filters will be used on the amplifier output to reduce harmonics to acceptable levels, and the amplifier must operate continuously at rated output power when harmonics are reflected back into it.
