Maldon, Essex – CML Microcircuits, a world-leader in the design, development and supply of low-power analogue, digital and mixed-signal semiconductors for telecommunications systems globally, is pleased to announce the release of a new range of RF Building Blocks: RF Power Amplifiers.
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.
