RF2189
3V, 2.5GHZ LINEAR POWER AMPLIFIER
• 2.5GHz ISM Band Applications
• PCS Communication Systems
• Wireless LAN Systems
• Commercial and Consumer Systems
• Portable Battery-Powered Equipment
• Broadband Spread-Spectrum Systems
The RF2189 is a linear, medium-power, high-efficiency
amplifier IC designed specifically for low voltage opera-
tion. The device is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (HBT) pro-
cess, and has been designed for use as the final RF
amplifier in 2.5 GHz spread-spectrum transmitters. The
device is provided in a 16-pin leadless chip carrier with a
backside ground and is self-contained with the exception
of the output matching network and power supply feed
line.
• Single 3.3V Power Supply
• +25dBm Saturated Output Power
• 20dB Small Signal Gain
• High Power Added Efficiency
• Power Down Mode
• 1800MHz to 2500MHz Frequency Range
