• EN202 (MAC/BB)
The EN202 is a highly integrated, triple-mode wireless LAN medium access control (MAC) and baseband (BB) chip, compatible with 802.11a/b/g wireless standards. Envara's EN202 chip is incorporated into its WiND502 and WiND512 wireless LAN chipset solutions, enabling a clear migration path for applications using 802.11g technology to advanced 802.11a/g based solutions. The EN202 contains two modems. An orthogonal frequency division multiplexing (OFDM) modem is compatible with the 802.11a and 802.11g and supports multiple data rates of up to 54 Mbps. A direct sequence spread spectrum/ complementary code-keying (DSSS/CCK) modem supports the 802.11b standard and supports multiple data rates of up to 11 Mbps. The inherent flexibility of the chip supports many advanced MAC features such as improved security, low power consumption, system stability and multimedia support. Key Features Built-in 802.11a / 802.11g and IEEE 802.11b compatible dual-mode OFDM and DSSS/CCK modems. Built-in 802.11 MAC, to support IEEE 802.11 MAC extended features such as Security (802 11i, and WPA), QoS (802.11e and WPA), and DFS/TPC for compatibility with Worldwide radio regulations (801.11h/d/j). External data bus, enabling connection to additional memory components as well as interface controllers, such as USB2.0 transceivers Built-in A/D and D/A converters Low power consumption PCI and MII interfaces Applications WLAN network interface cards (NICs) CardBus, MiniPCI, Ethernet and USB 2.0 (adapter and dongle) reference designs WLAN access points (AP) Residential gateways

• EN303 (RFIC 2.4/5GHz)
The EN303 is a monolithic SiGe half-duplex RF multi-band transceiver designed to operate in either the 5GHz unlicensed frequency band (including all channels starting from 4.9GHz up to 5.9GHz) or in the 2.4GHz unlicensed frequency band. As an integral part of Envara's WiND502 triple-mode chipset, EN303 enables a very low-cost implementation of wireless LAN (WLAN) equipment such as network interface cards and access points. EN303 is compatible with 802.11a, 802.11b and 802.11g international wireless standards. Key Features One-World support - Operates within either 4.900~5.825 GHz or 2.412~2.484 GHz frequencies - supporting 802.11h/g/j requirements Reduced BOM & small footprint On-chip VCOs, synthesizer, LNAs Envara's patented Enhanced Zero IF (EZ-IF) architecture enables simpler integration and lower cost implementation by not requiring external IF or baseband filters High Performance High input dynamic range Excellent interference resilience Improved sensitivity; greater range Power management includes 'stand-by' mode to maximise power efficiency. Applications WLAN interface cards: MiniPCI, USB 2.0, Ethernet and CardBus PC cards Access points (AP) Residential gateways

• EN313 (RFIC 2.4GHz)
The EN313 is a monolithic SiGe half-duplex RF transceiver designed to operate in the 2.4GHz unlicensed frequency band (2.412 - 2.484GHz). As an integral part of Envara's WiND512 chipset, EN313 enables a very low-cost implementation of wireless LAN (WLAN) Network Interface Cards (NICs) and Access Points (APs). EN313 is compatible with the 802.11g international wireless standard. Key Features Operates within 2.412~2.484 GHz frequencies – supporting 802.11h/g/j requirements Reduced BOM & small footprint On-chip VCOs, synthesizer, LNAs Envara's patented Enhanced Zero IF (EZ-IF) architecture enables simpler integration and lower cost implementation by not requiring external IF or baseband filters High Performance High input dynamic range Excellent interference resilience Improved sensitivity; greater range Power management includes 'stand-by' mode to maximise power efficiency.
