Product Description
The RF2127 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 1800MHz digital PCS phone transmitters
requiring linear amplification operating between
1800MHz and 1900MHz, with over 100mW transmitted
power. It will also function as the driver stage for the
RF2125 high power amplifier. A simple power down func-
tion is included for TDD operation.
