Product Description

The RF2128 is a medium-power, high-efficiency, linear amplifier IC. The device is manufactured on an advanced Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and has been designed for use as the final RF amplifier in 2.45GHz ISM applications such as WLAN and POS terminals. The part also will function as the final stage in digital PCS phone transmitters requiring linear amplification operating between 1900MHz and 2200MHz, with over 100mW transmitted power, or as the driver stage for the RF2125 high power amplifier. A simple power down function is included for TDD operation.
