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.
