Dual Band Direct Conversion Transceiver

The Intersil ISL3690 is a highly integrated UHF2 process, DUAL BAND direct conversion transceiver and is part of a 2.4/5.2GHz, IEEE802.11a/b/g compliant radio chipset. The ISL3690 directly interfaces with Intersil’s ISL3890 Medium Access Controller with Integrated Baseband processor. The addition of Intersil’s ISL3990 power amplifier and ISL3090 10GHz VCO completes a WLAN transceiver application.
