描述 Description

The SE5502L is a complete 802.11a/b/g/n WLAN RFfront-end module providing all the functionality of thepower amplifiers, filtering, power detector, T/R switch,diplexers, LNA and associated matching. TheSE5502L provides a complete 2.4 GHz and 5 GHzWLAN RF solution from the output of the transceiverto the antenna in an ultra compact form factor.

Designed for ease of use, all RF ports are matched to50 Ω to simplify PCB layout and the interface to thetransceiver RFIC. The SE5502L also includes atransmit power detector with 20 dB of dynamic rangefor each transmit chain. Each transmit chain has aseparate digital enable control for transmitter powerramp on/off control. The power ramp rise/fall time isless than 0.7 μsec.

The device also provides a notch filter from 3.260-3.267 GHz and 3.28-3.89 GHz prior to the input ofeach 2.4 GHz and 5 GHz power amplifiers,respectively.

The SE5502L packaged in 4mm x 4mm x 0.9mm,Halogen free, Lead free, ROHS compliant, MSL 3QFN package.

簡介

SE5502L屬于RF/IF射頻/中頻RFID的射頻前端（LNA+PA）。由制造生產(chǎn)的SE5502L射頻前端（LNA + PA）本系列中的產(chǎn)品是各種集成電路，其中集成了射頻 (RF) 信號鏈連接到系統(tǒng)天線的部分中常見的一種或多種功能，如低噪聲放大器 (LNA) 和可編程放大器 (PA)。任何給定器件所含的實際功能各不相同，相比旨在提供更高應(yīng)用靈活性的器件，針對相對較窄應(yīng)用的器件通常集成更大一部分必要的信號鏈。
