CMX90A004 2W 860 –960 MHz Power Amplifier
The CMX90A004 is a two-stage, fully matched MMIC PA delivering +32.5dBm of saturated power for use in the 860 – 960 MHz frequency range, applicable to license-free bands.
The device is optimised for maximum efficiency at collector voltages of 2.7–4.5V, making it suitable for systems operating from a single-cell Li-Ion battery.
CMX90A004 is highly integrated for ease of use, minimising external component count and reducing board area. RF input and output matching is incorporated on-chip, as well as active bias circuitry and an input DC-blocking capacitor.
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.
