Direct Conversion Transceiver
2.4GHz, IEEE802.11b/g compliant radio chipset. The
ISL3680 directly interfaces with Intersil’s ISL3880 Medium
Access Controller with Integrated Baseband processor. The
addition of Intersil’s ISL3980 power amplifier and ISL3090
10GHz VCO completes a WLAN transceiver application.
