RF2128
MEDIUM POWER LINEAR AMPLIFIER
• PCS Communication Systems
• 2.5GHz ISM Band Applications
•Wireless LANs
• Commercial and Consumer Systems
• Portable Battery Powered Equipment
The RF2128 is a medium-power, high-efficiency, linear
amplifierIC. The deviceis manufacturedonanadvanced
Gallium Arsenide Heterojunction Bipolar Transistor (HBT)
process, and has been designed for use as the final RF
amplifier in 2.45 GHz 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
2200 MHz, with over 100 mW transmitted power, or as the
driver stage for the RF2125 high power amplifier. A sim-
ple power down function is included for TDD operation.
• Single 3.0V to 6.5V Supply
• 100mW Linear Output Power
• 25dB Small Signal Gain
• 30% Efficiency
• Digitally Controlled Power Down Mode
• 1900MHz to 2500MHz Operation
