The RF3105 is a high-power, high-efficiency linear amplifier module from RF Micro Devices. It is targeted at 3V handheld systems and is used as the final RF amplifier in dual-mode 3V CDMA/AMPS handheld digital cellular equipment, spread-spectrum systems, and other applications in the 824MHz to 849MHz band.
The RF3105 is a high-power, high-efficiency linear amplifier IC manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process. It is designed for use as the final RF amplifier in dual-mode 3V CDMA/AMPS handheld digital cellular equipment and spread-spectrum systems within the 824MHz to 849MHz band. The device features a digital bias control voltage for low current in standby mode and is self-contained with 50Ω input and output matching.
