Introduction
The BGA622 is an easy-to-use, versatile and flexible low-cost Low Noise Amplifier
(LNA) MMIC designed for the high linearity and sensitivity requirements of existing and
next - generation wireless applications including GSM, 900 MHz ISM, GPS, UMTS and
Wireless LANs. Based on Infineon’s cost-effective 70 GHz fT Silicon-Germanium (SiGe)
B7HF bipolar process technology, the BGA622 offers a 1.1 dB noise figure and 15 dB of
gain at 2.1 GHz for high performance, cost-effective mobile communications
applications. BGA622 offers impressive noise figure performance, particularly for a low-
cost, integrated MMIC. In the past, in-circuit noise figures approaching 1.0 dB at 2 GHz
were possible only for more expensive GaAs-based, fully discrete solutions utilizing
narrowband impedance matching and higher external parts count. The BGA622
combines the excellent noise figure advantages of a high-performance discrete solution
with the ease-of-use, low parts count, and diminished risk and reduced system
development time made possible by a MMIC approach.
