The device is ideally suited for use in VHF and UHF frequency bands up 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. External components are required to match the device input and output ports to 50 Ohms. The CMX901 is available in a small footprint 5mm x 5mm, low thermal resistance 28-pin WQFN package making it ideal for small form factor...
