| Product Brief September 2003 WaveLANTM WL54040 Dual-Band Wireless LAN Transceiver 1 s Features Direct-conversion receiver for IEEE(R) 802.11b and low-IF receiver for IEEE 802.11a/g with integrated channel filter and programmable gain control. dc offset cancellation. Synthesizer with integrated VCO, PLL, 40 MHz crystal oscillator with digital frequency calibration. I-Q differential interface for RX and TX, multiplexed for IEEE 802.11a/b/g. Direct modulation transmitter with programmable output power -10 dBm to 0 dBm. High sensitivity (under normal operating conditions): -- IEEE 802.11b mode: -88 dBm for 11 Mbits/s. -- IEEE 802.11a and IEEE 802.11g modes: -74 dBm for 54 Mbits/s. No external SAW filter required. Low BOM, low external component count. 0.25 m BiCMOS technology. Three-wire bus control. Supply voltage 3.0 V--3.6 V. Alternative direct supply of regulated supply voltage 2.5 V--2.7 V. Two integrated voltage regulators (LDO). Powerdown modes. Operational temperature -30 C to +85 C. The WaveLAN WL54040 is a low-power, high-performance dual-band transceiver for the IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g wireless LAN standards. The WL54040 is designed to form a complete Agere IEEE 802.11a/b/g chip set in combination with the WL64040 multimode baseband processor, the WL60040 WMAC, and the WL54240 dual-band power amplifier. The WL54040 is designed in 0.25 m BiCMOS technology. It is capable of automatically switching between low intermediate-frequency conversion (low-IF) for OFDM and direct down conversion for DSSS/CCK modulation, enabling the device to achieve optimal throughput for all of the IEEE 802.11 standards. Specifically, low-IF conversion guards against dynamic range degradation, an inherent limitation of direct-down OFDM architectures, to provide improved system performance. s s s s s s s s s s s 3 Description s s s 2 s s Wireless LAN Applications High data-rate multimode applications.
