The CMX902 is a three stage high-gain and high efficiency RF power amplifier. The device is ideally suited for use in VHF and UHF frequency bands up to 700MHz. The first and second stages of the amplifier operate in a class-A and class-AB mode respectively, and the third stage operates in a class-C mode for maximum efficiency. External components are required to match the device input and output ports to 50 Ohms. The CMX902 is available in a small footprint 5mm x 5mm, low thermal resistance 28-pin WQFN package making it ideal for small form factor applications such as data modules as well as handheld radio terminals.
