W-CDMA LINEAR VARIABLE GAIN
DRIVE R AMPLIFIER
PA Driver Amplifier for W-CDMA Handsets
General Purpose Driver Amplifier
The RF2681 is a linear variable gain amplifier specifically
designed for PA driver applications in W-CDMA handsets.
The device maintains excellent linearity over a 30dB gain
control range, while providing a maximum of 26dB gain.
The IC is manufactured on an advanced Gallium Ars-
enide Heterojunction Bipolar Transistor Process and is
provided in an extremely small 3mmx3mm, 12-pin, lead-
less chip carrier.
