LX5506B

The LX5506B 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, onchip input matching and output prematching. It also features an on-chip output power detector to help reduce BOM cost and PCB board space for system implementations. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates with a single positive voltage supply of 3.3V (nominal), with +26dBm of P1dB and up to 25dB power gain in the 5.15 - 5.85GHz frequency range with a simple output matching capacitor pair. LX5506B is available in a 16-pin 3mmx3mm micro-lead package (MLP). The compact footprint, low profile, and excellent thermal capability of the MLP package makes the LX5506B an ideal solution for broadband, high-gain power amplifier requirements for IEEE 802.11a, and HiperLAN2 portable WLAN applications.
