The Model 125W1000A from AR RF/Microwave Instrumentation is a Solid-State Power Amplifier that operates from 80 to 1000 MHz. It delivers an output power of more than 125 W with a small signal gain of 57 dB. This class-A amplifier is 100% mismatch tolerant and has built-in fault monitoring & protection from input overdrive beyond 0 dBm as well as protection from various failure conditions including over-temperature and power supply faults. It has spurious levels of -73 dBc and harmonics of -30 dBc. The SSPA is ideal for use as a driver in testing wireless and communication components and also for EMC test applications where continued operation into high VSWR loads including open and short circuits is required.

The 125W1000A has a front panel display indicates the operational status and fault conditions. It can be controlled manually via a front panel display and remotely via GPIB/IEEE-488, RS-232, fiber-optic serial, USB, or Ethernet interfaces. It is available in a 3U, rack-mount enclosure that measures 48.3 x 13.4 x 65.3 cm with N-type (female) connectors and is ideal for 5G testing, EMC (military, aviation, automotive, commercial), radiated & conducted EMC testing, general purpose, antenna, and component testing applications.

The export classification for this equipment is EAR99. This SSPA requires an AC supply from 100 to 240 V and consumes less than 600 W of power.
