LX5503ELQ数据手册Microchip中文资料规格书

描述 Description

For new designs consider the LX5530LQ.The LX5503E is a power amplifier optimized for high-efficiency low power applications in the FCC Unlicensed National Information Infrastructure (U-NII) band, Europe HyperLAN2, and Japan WLAN in the 4.9-5.85GHz frequency range. The PA is implemented as a two-stage monolithic microwave integrated circuit (MMIC) with active bias and input/output pre-matching. The device is manufactured with an InGaP/GaAs Heterojunction Bipolar Transistor (HBT) IC process (MOCVD). It operates at a single supply of 3.3V with +26dBm of P1dB, and power gain of 21dB between 4.9-5.35GHz and 16dB up to 5.85GHz. For +18dBm OFDM output power (64QAM, 54Mbps), the PA provides a very low EVM (Error Vector Magnitude) of 3%, and consumes 150mA total DC current. The LX5503E is available in a 16-pin 3x3mm2 micro-lead package (MLP). The compact footprint, low profile, and excellent thermal capability of the micro-lead package make the LX5503E an ideal solution for broadband, medium-gain power amplifier requirements for IEEE 802.11a, and HiperLAN2 portable WLAN applications.  ROHS, PB Free
