Matched to 5 at all RF inputs and outputs, the part requires no additional RF matching components offchip, making the AWL992 the world s simplest dual band PA IC implementation available. The PA exhibits unparalleled linearity and efficiency for IEEE 2.11g, 2.11b and 2.11a WLAN systems under the toughest signal configurations within these standards. The power detectors are temperature compensated on chip, enabling separate singleended output voltages for each band with excellent accuracy over a wide range of operating temperatures. The PA is biased by a single +3.3 V supply and consumes ultralow current in the OFF mode. The AWL992 is manufactured using advanced InGaP HBT technology that offers stateoftheart reliability, temperature stability and ruggedness. The IC is provided in a mm x mm x.9 mm LPCC package optimized for a 5 system.
