详细描述
The RF6281 is a high-power high-efficiency linear amplifier module specifically designed for 3V handheld systems. This amplifier uses a balanced architecture which makes the PA load insensitive and therefore eliminates the need for an isolator. The device is manufactured on an advanced eighth generation GaAs HBT process and was designed for use as the final RF amplifier in 3V UMTS handheld digital cellular equipment spreadspectrum systems and other applications in the 1710MHz to 1980MHz band (Bands I II III IV IX). The RF6281 has an analog bias control pin to reduce idle current at low power levels. The RF6281 is assembled in 16-pin 4mm x 4mm laminate package.
