BGA619

The BGA619 is an easy-to-use, low-cost Low Noise Amplifier (LNA) MMIC designed for use in today's PCS systems which require excellent linearity in each of several gain step modes. Based on Infineon's cost-effective 70 GHz fT Silicon-Germanium (SiGe) B7HF bipolar process technology, it offers a 1.5 dB noise figure and 14.9 dB of gain at 1.96 GHz with a current consumption of 6.5 mA in high gain mode. BGA619 offers impressive IIP3 performance of 7 dBm in High Gain mode, particularly for a three-gain step, low-cost, integrated MMIC.

The new LNA BGA619 incorporates a 50 Ω pre-matched output with an integrated output DC blocking capacitor. The input is pre-matched, requiring an external DC blocking capacitor. An integrated, on-chip inductor eliminates the need for an external RF choke on the voltage supply pin. The operating mode of the device is determined by the voltage at the GS-pin. An integrated on/off feature provides for low power consumption and increased stand by time for PCS cellular handsets.
