The CMPA5259025S from MACOM is a GaN HEMT-based MMIC Power Amplifier that operates from 5.2 to 5.9 GHz. It delivers an output power of 40 W with a gain of 25 dB and has a power added efficiency (PAE) of more than 53%. This MMIC has a two-stage reactively matched amplifier design which enables wide bandwidths to be achieved in a small footprint while maintaining high gain and efficiency. It requires a DC supply of 28 V and consumes 250 mA of current.
The amplifier is designed primarily for use as an output stage for highly integrated AESA radar type architectures. In addition, the high gain makes it suitable as a drive stage for a multi-device line-up using the MACOM high power IMFETs as the final stage. The CMPA5259025S is available in a QFN package that measures 5 x 5 mm and is ideal for civil and military pulsed, and radar amplifier, aerospace, and defense applications.
