Amplifier Research 10W1000A

The Amplifier Research 10W1000A is a solid-state, air-cooled RF power amplifier delivering 10 W continuous-wave output across 1 MHz to 1 GHz. Built on push-pull circuitry in high-power stages, it achieves 40 dB minimum gain with exceptionally low distortion and load-mismatch immunity. The amplifier accepts input signals up to 1 mW for rated output and saturates at 18 W typical, making it equally capable in EMC testing, communications systems, antenna characterization, component validation, and RF source applications.

Its self-contained design eliminates external cooling infrastructure while internal protection - crowbar circuits, over-temperature sensing, and unconditional stability against any source or load VSWR - ensures operation under worst-case mismatch conditions, including shorted or open cables, without shutdown or damage.
