DESCRIPTION

The STMicroelectronics STLC8100 wireless LAN

RF device is an integrated Direct Conversion Tx/

Rx, with on-chip synthesizer for channel selection

across worldwide 2.4 and 5GHz bands.

It is designed to interface directly with STMicro-

electronics STLC8201 series Baseband/MAC pro-

cessors to provide a complete wireless LAN

solution

compliant

with

the

IEEE802.11a,

IEEE802.11g and IEEE802.11b standards.

The STLC8100 is a fully integrated single chip RF

front end supporting the standards at both 2.4GHz

and 5GHz. A direct conversion architecture is

used on both Transmit and Receive paths requir-

ing no bulky or expensive intermediate frequency

filters. Separate Low Noise Amplifiers for 2.4GHz

and 5GHz bands delivers excellent receiver sensi-

tivity improving link budget and maximizing range

and data rate. Independent RF transmitter outputs

are provided for the 2.4GHz and 5GHz bands to

ensure maximum flexibility. A fully integrated syn-

thesizer supplies the local oscillator inputs for both

RX and TX paths in both bands. Designed in

CMOS for cost optimization, the single chip

STLC8100 supports frequency ranges in both

2.4GHz and 5GHz bands for 802.11 a, b and g glo-

bal market compliance.

The STLC8100 supports the band-interleaving

feature enabling low cost access points through

support of simulataneous clients in both bands us-

ing a single radio card.
