CML Micro CMX90A004 2W 860MHz to 960MHz Power Amplifiers
CML Micro CMX90A004 2W 860MHz to 960MHz MMIC Power Amplifiers are two-stage, fully matched MMIC PAs delivering +32.5dBm of saturated power for use in the 860MHz to 960MHz frequency range, applicable to license-free bands. CMX90A004 amplifiers are highly integrated for ease of use, minimizing external component count and reducing board area. RF input and output matching are incorporated on-chip and active bias circuitry and an input DC-blocking capacitor.
The devices are optimized for efficiency at low collector voltages of 2.7V to 4.5V, making them suitable for systems with supercapacitor backup storage, thus extending the discharge period or battery life. The CMX90A004 is available in a 4mm x 4mm VQFN-16 package.
Using advanced GaAs HBT technology to provide a combination of high efficiency and gain, the CMX90A004 is intended as a high-power final stage ISM band PA in wireless applications.
