GENERAL DESCRIPTION

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

delivers 43 dBm (20 W) with more than 43 power added efficiency

(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 manufacturing

techniques.
