CML expands RF power amp family with CMX902 IC

CML Microcircuits » CMX902

CML expands RF power amp family with ultra-compact device for 130 MHz to 700 MHz CMX902 IC combines high gain and high efficiency with small footprint.

CML Microcircuits - CMX902

The CMX902 is ideally suited for VHF and low UHF radio applications such as data modules, marine VHF communications, general-purpose, low-power RF transmitters and radio applications used in Industrial Internet of Things (IIOT) systems. High power added efficiency (up to 60% at VHF) is a key feature of this device, supporting low-voltage 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, allowing designers to adjust for maximum power and efficiency at the desired operating frequency.

The CMX902 offers high power gain up to 39 dB and is available in a small footprint 5 mm × 5 mm low thermal resistance 28-pin WQFN package. This makes it ideal for low-power and small form factor applications.
