| Product Brief September 2003 WaveLANTM WL54240 Dual-Band Power Amplifier 1 Features ! ! . Enhanced 0.25 m bipolar technology (SiGe). Operating frequency: -- 2.4 GHz ~ 2.5 GHz -- 5.15 GHz ~ 5.85 GHz Dual-band and dual-mode solution. Single 3.3 V supply voltage. High linear PA for OFDM and DSSS/CCK modes. Short TX/RX turnaround times. Low EVM for QAM64/54 Mbits/s. Standby function. Analog power control for both bands. Digital band select (2.4 GHz/5 GHz). Digital standby mode. Tiny mini-VQFN-24/0.5 package. Integrated power detector with buffer for control loop. Bands: -- 2.4 GHz: PSat = 30 dBm. -- 5 GHz: PSat = 27 dBm. 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 (R) 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. ! ! ! ! ! ! ! ! ! ! ! ! 3 Description 2 Wireless LAN Applications ! ! ! ! ! !
