The BGA619 is an LNA MMIC designed for use in today’s PCS systems which require excellent linearity in each of several gain step modes.
The document introduces the BGA619, a low-cost Low Noise Amplifier (LNA) MMIC designed for 1900 MHz PCS wireless frontends. It utilizes Infineon's 70 GHz fT Silicon-Germanium technology to offer a noise figure of 1.5 dB and high linearity with an IIP3 of 7 dBm in High Gain mode.
The device offers three gain steps and one off-mode: High Gain, Mid Gain, Low Gain, and OFF Mode.
The typical supply voltage used for measurements in this document is 2.78 V.
The BGA619 consumes 6.5 mA when operating in High Gain mode.
