LX5537LQ中文资料WLAN Power Amplifiers (PA)数据手册Microchip规格书

描述 Description

The LX5537 is a power amplifier optimized for 802.16e(WiMAX/WiBro) and 802.11b/g/n applications in the 2.3-2.7 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). It operates with a single positive voltage supply of 3-4.2V, and provides power gain of 31dB and output powers of +23.5dBm at 3.6V and +25 dBm at 4.2V for 2.5% EVM in the 2.5-2.7GHz. LX5537 also features an on-chip power detector at the output port of the PA to help reduce BOM cost and PCB space for implementation of power control in a typical wireless system. The 26dB attenuation function can optionally be used to reach low gain mode. The LX5537 is available in a 16-pin 3mm x 3mm quad flat no lead package (QFN 3×3-16L). The compact footprint, low profile, and excellent thermal capability make the LX5537 an ideal solution for WiMAX/WiBro as well as 802.11b/g/n applications.  ROHS, PB Free

简介

LX5537LQ属于RF/IF射频/中频RFID的射频放大器。由制造生产的LX5537LQ射频放大器在射频应用中，射频放大器产品可用于信号增益和缓冲。这些产品与通用运算放大器的不同之处在于，它们通常适用于更高的频率，更倾向于提供不可调节的固定增益，并且输入或输出阻抗值符合常用传输线特性阻抗。
