Product Description
The RF3183 is a high power amplifier module with integrated power control. The input and out-
put terminals are internally matched to 50. The amplifier devices are manufactured on an
advanced Gallium Arsenide Heterojunction Bipolar Transistor (GaAs HBT) process. The module
is designed to be the final amplification stage in a dual-mode GSM/EDGE mobile transmit
lineup operating in the 824MHz to 915MHz (low) and 1710MHz to 1910MHz (high) bands
(such as a cellular handset). Band selection is controlled by an input on the module which
selects either the low or high band. The device is packaged on a 5mmx5mm laminate module
with a protective plastic over-mold. The RF3183 features RFMD’s latest integrated power flat-
tening circuit, which significantly reduces current and power variation into load mismatch. The
RF3183 provides excellent ESD protection at all the pins. The RF3183 also provides integrated
VRAMP rejection filter which improves noise performance and transient spectrum.
