* Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.




Description

The WaveLAN WL54240 is an extremely linear, highpower amplifier for WLAN applications in the 2.4 GHz and 5 GHz bands. It has analog power control for both bands as well as an on-chip power detector to compensate the variability of transmit gain. The WL54240 is designed to form a complete IEEE ® 802.11a/b/g WLAN chip set in combination with the WL60040 multimode MAC, the WL64040 baseband, and the WL54040 transceiver.

The WL54240 is a dual-band and dual-mode power amplifier that combines the functionality of two devices (two frequency bands) in one package. This reduces the total board space required and reduces the total bill of materials to a minimum. Essential internal blocks can be used alternately by both amplifier path, providing optimum product synergy.
