GENERAL DESCRIPTION

The ADPA1122 is a gallium nitride (GaN), power amplifier that

delivers 43 dBm (20 W) with more than 43% power added efficien-

cy (PAE) across its 8.2 GHz to 11.8 GHz frequency range. The

ADPA1122 provides ±0.5 dB of gain flatness from 9.6 GHz to 11

GHz.

The ADPA1122 is optimized for pulsed applications such as military,

marine, and weather radar.

The ADPA1122 is packaged in an 18-terminal, 7 mm × 7 mm,

ceramic leadless chip carrier with heat sink [LCC_HS] that exhibits

low thermal resistance and is compatible with surface-mount manu-

facturing techniques.
