Product Description

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

Designed for ease of use, all RF ports are matched to 50 Ω to simplify PCB layout and the interface to the transceiver RFIC. The SE5502L also includes a transmit power detector with 20 dB of dynamic range for each transmit chain. Each transmit chain has a separate digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is less 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 of each 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 3 QFN package.

SE5502L-R屬于RF/IF，射頻/中頻和 RFID > 射頻前端（LNA + PA）。美國思佳訊公司制造生產(chǎn)的SE5502L-R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(shí)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。
