Power amplifier CMX90A004

RFMMIChigh-power

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. Features Output power 32.5 dBm @ 3.6 V Input and output matched to 50 Ω Small signal gain 30 dB High PAE of 49% Shut-down and output power control Applications Automatic meter readers (AMR) Smart meters Wireless modules UHF RFID readers Final stage PA Internet of Things (IoT) 868 / 915 MHz ISM Li-Ion battery powered systems Power Supply Requirement 2.7 V – 4.5 V
