RFIC Solutions Inc. Low Noise Amplifier Description . Preliminary Datasheet RGLNA01 Functional Diagram . The RGLNA01 is 0.7 to 3.0 GHz high efficiency GaAs Enhancement mode pHEMT Low Noise Amplifier IP Block .The device is designed for use in the IEEE 802.11b/g, PCS, PHS and Cellular system. The die area of RGLNA01 is 0.8 mm x 0.7 mm, with on chip input and output matching components. This makes it suitable for being packed in small QFN Packages. It requires a single +3.0 Volt supply and consumes only 15 mA current. There is good match between the measured and simulated results as shown below.
