AT76C503 is a sing le chip c ontrol ler that pro vides al l processin g
and functionality nee ded f or the MAC protoco l of wireless LANs .
A T76C503 contains a USB Bus interface, a MAC control unit and
a physical attachm ent interface(PAI). The PAI supports the new
5.5 and 11Mbps WLAN physical interfaces, and the IEEE 802.11
DSSS physical interfaces.
HFA3861B Direct Sequence Spread Spectrum (DSSS)
baseband processor is part of the PRISM 2.4GHz WLAN Chip set
and contains all the functions necessary for a full or half duplex
packet baseband transceiver. The HFA3861B has on-board A/D’s
and D/A for analog I and Q inputs and outputs for HFA3783.
HFA3783 is a highly integrated and fully differential SiGe
baseband converter for half duplex wireless application. It
features all the necessary blocks for quadrature modulation and
demodulation of “I” and “Q” baseband signals.
HFA3683A is a monolithic SiGe half-duplex RF/IF transceiver
designed to operate in the 2.4GHz ISM band.
HFA3983 is a 2.4GHz monolithic SiGe Power Amplifier designed
to operate in the ISM Band. It delivers a 18dBm(Typ.) of an output
power for the typical DSSS signal. The HFA3983 is housed in a
28 lead exposed paddle EPTSSOP package well suited for
PCMCIA board applications .
