RF2381
PCS/CELLULAR TDMA/CDMA/W-CDMA
LINEAR VARIABLE GAIN AMPLIFIER
• CDMA PCS/Cellular Handsets
• TDMA PCS/Cellular Handsets
• W-CDMA Handsets
The RF2381 is a linear variable gain amplifier suitable for
use in TDMA and CDMA systems in the cellular or PCS
band and for W-CDMA systems. The features of this
device include linear gain control, high gain, and high lin-
earity. The IC is manufactured on an advanced Gallium
Arsenide Heterojunction Bipolar Transistor (GaAs HBT)
process and is featured in an industry-standard miniature
6-lead plastic SOT package.
• 50dB Linear Gain Control Range
•22dB Maximum Gain
• Single 2.7V to 3.3V Supply
• 35mA Supply Current
• High Linearity
