The SE2521A80 provides a plete 2.4 GHz WLAN RF solution from the output of the transceiver to the antennas in an ultra pact 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 SE2521A80 also includes a transmitter power detector with 20 d B of dynamic range and a digital enable control for transmitter power ramp on/off control. The power ramp rise/fall time is 1 μsec typical. The SE2521A80 is pin for pin patible to Skyworks’ SE2521A34 for easy transition of medium power designs to higher power designs. The device also provides a notch filter from 3.2-3.3 GHz prior to the input of the power amplifier.
