RF5176中文资料威讯联合数据手册PDF规格书

Product Description

The RF5176 is a high-power, high-efficiency linear amplifier IC targeting 3V handheld systems. The device is manufactured on an advanced Gallium Arsenide Hetero junction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in 3V CDMA-2000 and W-CDMA handsets as well as other applications in the 1850MHz to 2000MHz band. The device is self-contained, and the output can be easily matched to obtain optimum power, efficiency, and linearity characteristics over all recommended supply voltages. The device has a continuously variable bias circuit to allow idle current to be optimized for a given output power.
