SK3875 T Datasheet
Advanced quad-band, compact 3V power amplifier module designed for mobile handset applications. The small size and high performance is achieved with high-reliability InGaP HBT technology. The module is fully integrated, providing a simple 50 0hms interface on all input and output ports. It includes internal closed-loop power control. No external matching or bias components are required. Despite its very compact size, the module has exceptional efficiency in all bands.
