Amplifier Research 50W1000

The Amplifier Research 50W1000 is a solid-state, air-cooled broadband amplifier engineered for RF and EMI susceptibility testing, antenna characterization, and component validation. Operating across 1 MHz to 1 GHz with 50 W CW minimum output and 47 dB gain, this self-contained unit delivers instantaneous bandwidth without band switching. Type N female connectors, 50 ohm impedance, and integrated protection circuits ensure reliable performance in demanding laboratory environments.
