BGA622

• Low Noise Amplifier for 800/900 MHz, GSM900, 900 MHz ISM, DCS1800, GPS,1900 MHz PCS, 2.1 GHz UMTS and 2.4 GHz Wireless LAN
• Long-Range Bluetooth applications requiring improved system sensitivity via use of an external LNA

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.
