描述 Description

Please note: this product is being discontinued and is not recommended for new designs.

The SE5512L 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 SE5512L 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 SE5512L 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 SE5512L packaged in 4mm x 4mm x 0.9mm, Halogen free, Lead free, ROHS compliant, MSL 3 QFN package.

简介

SE5512L属于RF/IF射频/中频RFID的射频放大器。由制造生产的SE5512L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。
