The LX5506 is a power amplifier designed for the FCC Unlicensed National Information Infrastructure (U-NII) band, HyperLAN2 and Japan WLAN applications in the 4.9-5.95 GHz frequency range. The PA is implemented as a three-stage monolithic microwave integrated circuit (MMIC) with active bias and complete on-chip input matching. The

device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates at a single positive voltage supply of 3.3V (nominal), with +26dBm of P1dB and up to 23dB power gain in the 5.15 - 5.85GHz frequency range with a simple output matching capacitor pair.
