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 sim-

ple power down function is included for TDD operation.
