| RFIC Solutions Inc. Power Amplifier Description . Preliminary Datasheet RGPA03 Functional Diagram . The RGPA03 is a 3.4 to 3.6 GHz high efficiency GaAs Enhancement mode psuedomorphic high electron mobility transistor MMIC Power Amplifier. It has been designed for use in the 3.5 GHz WiMax systems. The part is matched at the input and output so no additional RF matching components are required. The PA exhibits unparalleled linearity and efficiency for this Band. The part is biased by a single +3.3V supply. . Applications. * WiMax Transceivers * Broadband Wireless Application . Key Features. . * High Gain, High Performance * Linear Gain around 25 dB * Output Power in the range of 20 dBm * Small Die Area Electrical Specifications. .
