The RF2302 is a broadband linear variable gain amplifier
that was designed specifically for digital communications
systems that require linear amplification over a wide gain
control range. It is suitable for use in CDMA or TDMA sys-
tems in the cellular or PCS band, in DAMPS systems,
and in PDC systems. Operating supply voltage ranges
from 3V to 6V. The device operates over a large fre-
quency band, from 100MHz to 2000MHz, and is tuned to
a specific frequency band with an output bias feed induc-
tor and blocking capacitor. Bias optimization may be
achieved by adjusting the voltage to pin 8 (PD). The IC is
manufactured on an advanced Gallium Arsenide Hetero-
junction Bipolar Transistor (GaAs HBT) process and is
featured in a new standard miniature 8-lead plastic
MSOP package.
