Product Description

4

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.
