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 STMicroelectronics STLC8201 series Baseband/MAC processors 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 requiring no bulky or expensive intermediate frequency filters. Separate Low Noise Amplifiers for 2.4GHz and 5GHz bands delivers excellent receiver sensitivity 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 synthesizer 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 global market compliance.

The STLC8100 supports the band-interleaving feature enabling low cost access points through support of simulataneous clients in both bands using a single radio card.
