CML Micro CMX90A002 2-Stage MMIC Power Amplifiers
CML Micro CMX90A002 2-Stage MMIC Power Amplifiers are fully matched devices designed for 860MHz to 960MHz ISM-band and sub-1GHz wireless applications. Housed in a compact 3mm × 3mm VQFN-16 package, the CMX90A002 power amplifiers deliver up to 32.5dBm saturated output power with up to 49% power-added efficiency (PAE) while operating from a wide 1.9V to 4.5V supply range. Integrated 50Ω input/output matching, on-chip bias circuitry, and an input DC-blocking capacitor reduce external component requirements, simplifying RF design and minimizing PCB area.
Optimized for battery-powered and supercapacitor-backed systems, the CML Micro CMX90A002 amplifiers offer high gain, automatic shutdown, and output power control, making the devices well-suited for smart meters, automatic meter readers (AMR), industrial Internet of Things (IIoT) devices, wireless modules, asset-tracking equipment, and 868MHz/915MHz ISM applications. The combination of high output power, a compact footprint, and broad supply-voltage support enables designers to create space-efficient wireless systems while maintaining strong RF performance across a wide range of power architectures.
