The device exhibits industry-leading power added efficiency under 82.11b and 82.11g modulated signals. The RF input match and output matches are integrated on chip as are the second and third stage bias chokes. The power amplifier is manufactured using TriQuint s InGaP HBT process and is packaged in an industry standard 3mm x 3mm VQFN-16 Pb-Free package.
