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.
