125 and 250 Watt CW 6 – 18 GHz Class A Solid State Amplifiers




AR 2023 Catalog


AR RF/Microwave added two new 6 to 18 GHz Class A High Power Solid State Amplifiers

The new 250S6G18C is a Solid-State Amplifier that operates from 6 to 18 GHz and delivers an output power of 250 W.  The new 125S6G18CI delivers an output power of 125 Watt.125 W CW from 6.0 – 12.0 GHz.The new amplifiers join the 20, 40 and 75 Watts 6-18 GHz models that have been introduced earlier

A front panel display indicates the operational status and fault conditions. All amplifier control functions, and status indications are available remotely using GPIB/IEEE-488, RS-232, fiber-optic serial, USB, or Ethernet. Interface connectors are located on the back panel. Local and remote operation is managed by a switch on the front panel.


Excellent TWTA Replacement

These class-A amplifier are excellent alternative to TWTA and provides high linearity, low spurios and second and third harmonics better than – 20 dBc without external filtering.



It is designed for EMC RI, CI testing (MIL-STD-461, RTCA/DO-160), antenna testing, and microwave component testing. The amplifier has full VSWR mismatch tolerance with protection circuits.This is a multiple purpose amplifier. The low level of spurious signals and linearity make it ideal for use as a driver in testing wireless and communication components and subsystems. By covering such a wide bandwidth, it is suitable for a variety of communication technologies such as CDMA, W-CDMA, TDMA, GSM, UWB, WiMAX etc.
