The 250S6G18C from AR RF/Microwave Instrumentation is a Solid-State Amplifier that operates from 6 to 18 GHz. It delivers an output power of 250 W with second and third harmonics of better than -20 dBc without external filtering. This class-A amplifier is an alternative to TWTA and provides high linearity to support all wireless modulation standards. 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.
