Model AML618P4015 is a gallium-nitride (GaN) power amplifier designed to provide 20 W output power from 6 to 18 GHz. The high-power-density amplifier achieves power-added efficiency (PAE) of typically 12% in a package measuring just 2.45 x 2.09 x 0.41 in. It achieves 40-dB minimum small-signal gain across its full operating bandwidth and operates from a +32-VDC supply. The rugged amplifier is supplied in a hermetic aluminum housing with field-removavble female SMA connectors. It features a transistor-transistor-logic (TTL) controlled muting function capable of 200-ns on/off speed. The amplifier has an operating temperature range of -40 to +85C.
