SE2568L中文资料5 GHz Power Amplifiers for Wi-Fi Connectivity数据手册Skyworks规格书

描述 Description

The SE2568L is a complete 802.11 b/g WLANdiscrete power amplifier. The device provides all thefunctionality of the power amplifier, power detector,filter, associated input, inter-stage and outputmatching in an ultra compact 2mm x 2mm x 0.9mmform factor.

The SE2568L is designed for ease of use, with all thecritical input and output matching integrated. TheSE2568L includes a transmitter power detector with20 dB of dynamic range and a digital Enable forpower on/off control. Harmonic filters and an input3.2GHz LO rejection filter are integrated on-chip. Thepower ramp rise/fall time is 0.7 µs typical.
