ADPA1122AEHZ-R7

RF Amplifiers Overview

The ADPA1122AEHZ-R7 is a single-stage, internally matched and AC-coupled GaN power amplifier designed for radar applications. It operates within the 8 GHz to 12 GHz frequency range, delivering a saturated output power of 20 W (43 dBm). The device achieves a typical Power Added Efficiency (PAE) exceeding 43% and provides approximately 20 dB of gain. It requires a 28 V supply voltage with a typical supply current of 200 mA. The component is housed in an 18-terminal ceramic leadless chip carrier package with a heat sink (LCC_HS), suitable for operation across a temperature range of -40°C to +85°C.
