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.
