Product Description
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.
