RF2145
DCS1800/1900 POWER AMPLIFIER
• 4.8V DCS1800/1900 Handsets
• 3V DECT Handsets and Base Stations
• Commercial and Consumer Systems
• Portable Battery Powered Equipment
TheRF2145 is ahighpower,highefficiency amplifier IC.
The device is manufactured on an advanced Gallium Ars-
enide Heterojunction Bipolar Transistor (HBT) process,
and has been designed for use as the final RF amplifier in
a 4-cell DCS1800 or DCS1900 handset. The device is
packaged in a 16-lead plastic package with wide ground
leads, and is self-contained with the exception of the out-
put matching network and power supply feed line. Only a
single positive voltage is required to operate with full
power and efficiency, and on-board power control and
power-down functions are provided.
• Single 4.8V Power Supply
• +32dBm Output Power
• 28dB Small Signal Gain
• 55% Power Added Efficiency
• Power Control
• 1700MHz to 1900MHz Frequency Range
