The LX5506E is a power amplifier optimized for the FCC Unlicensed National Information Infrastructure (U-NII) band, HyperLAN2 and Japan WLAN applications in the 4.9-5.85 GHz frequency range. The PA is implemented as a three-stage monolithic microwave integrated circuit (MMIC) with active bias, on chip input matching and output pre matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process

(MOCVD).
