SE2574L 2.4 GHz High Efficiency Wireless LAN PA
The SE2574L is a complete 802.11 b/g WLAN discrete power amplifier. The device provides all the functionality of the power amplifier, power detector, filter, associated input, inter-stage and output matching in an ultra compact 2mm x 2mm x 0.9mm form factor. The SE2574L is designed for ease of use, with all the critical input and output matching integrated. The SE2574L includes a transmitter power detector with 20 dB of dynamic range and a digital Enable for power on/off control. Harmonic filters and an input 3.2GHz LO rejection filter are integrated on-chip. The power ramp rise/fall time is 0.7 μs typical.
