RFPA2172
ISM Band 3.6V, 250mW AMP with
Analog Gain Control
The RFPA2172 is a medium-power high efficiency amplifier IC targeting
3.6 V handheld systems. The device is manufactured on an advanced
Gallium Arsenide Heterojunction Bipolar Transistor (HBT) process, and
has been designed for use as the final RF amplifier in 2.45 GHz
Bluetooth applications and frequency hopping/direct sequence spread-
spectrum cordless telephones or other applications in the 902 MHz to
928 MHz ISM band. The device is packaged in a compact 4 mm x 4 mm
QFN. The device features analog gain control to optimize transmit
power while maximizing battery life in portable equipment requiring up to
100 mW transmit power at the antenna port.
