详细描述
The RF6285 is a high-power high-efficiency multi-band 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 isolators. 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 spread-spectrum systems and other applications in the 824MHz to 915MHz and 1710MHz to 1980MHz band. The RF6285 has an analogbias control pin to reduce idle current at low power levels. The RF6285 isassembled in a 28-pin 5.5mm x 6.0mm laminate package.
