The SE2559L20 provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra compact form factor. The SE2559L20 is designed for ease of use, with all the critical matching and harmonic filtering integrated, offering a simple 50 Ω interface to the antenna. The SE2559L20 also includes a transmitter power detector with 20 dB of dynamic range and a digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is 0.5 μs typical. The device also provides a 3.2–3.3 GHz notch filter prior to the input of the power amplifier.
