An RF power amplifier (RF PA) is a key part of any RF transmitter line up with size, efficiency and overall performance being important factors.
The CMX901 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 from 130MHz to 950MHz.
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. The 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.
