50A250 Image

'The 50A250 from AR RF/Microwave Instrumentation is a portable, self-contained, air-cooled, solid-state power amplifier that operates from 10 kHz to 250 MHz. It delivers over 50 watts of CW output power and has a gain of more than 47 dB with a noise figure of 8 dB. It is available as a benchtop unit with N-type connectors and has a digital front panel display that indicates the operate status and fault conditions if an over-temperature or power supply fault has occurred. The unit can also be rack mounted after removing the cabinet.

This amplifier has built-in IEEE-488 (GPIB), RS-232, USB & Ethernet interfaces. It also has a safety interlock circuit for use with external safety switch interlocks. This circuit prevents the amplifier from going into operate mode unless the external connection is made. A jumper plug is provided for cases where this functionality is not needed.
