The CMX901 is the first product in its range to be released and is a three-stage wideband, high gain and high efficiency RF power amplifier IC operating over 130MHz to 950MHz. The device is ideally suited for use in VHF/UHF radio applications such as data modules, Marine VHF communications and RFID readers/writers used in Industrial Internet of Things (IIOT) systems. High power added efficiency supports battery powered applications.
The first and second stages of the amplifier operate in a class-A and class-AB mode respectively, and the third stage operates in class-C mode for maximum efficiency. Input and output matched circuits are implemented via external components and therefore can be adjusted to obtain maximum power and efficiency at the desired operating frequency.
The CMX901 is available in a small footprint 5mm x 5mm low thermal resistance 28-pin WQFN package making It ideal for small form factor applications.
