RF Micro Devices® 3V 900 MHz Linear Amplifier

The RF6100-2 is a high-power, high-efficiency linear amplifier module specifically designed for 3V handheld systems. The device is manufactured on an advanced third-generation GaAs HBT process and has been designed for use as the final RF amplifier in 3V IS-95/CDMA 2000 1x/AMPS handheld digital cellular equipment, spread-spectrum systems and other applications in the 824 MHz to 849 MHz band. The RF6100-2 has a digital control line for low power applications in order to lower quiescent current. The device is self-contained with 50Ω input and output that is matched to obtain optimum power, efficiency and linearity. The module is an ultra-small 4x4mm land grid array with backside ground. The RF6100-2 is footprint compatible with industry standard 4x4mm CDMA modules and requires only one decoupling capacitor.
