CML Microcircuits recently released a new range of RF power amplifiers. The CMX901 is a three-stage wideband, high-gain, high-efficiency RF power amplifier IC operating over 130 to 950 MHz. 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 amplifier’s first and second stages operate in a class-A and class-AB mode, respectively. The third stage operates in class-C mode for maximum efficiency. Input and output matched circuits are implemented via external components. They can be adjusted to obtain maximum power and efficiency at the desired operating frequency.
The CMX901 is available in a small footprint 5 mm × 5 mm low thermal resistance 28-pin WQFN package, which makes it ideal for small form factor applications.
