Dual Band Direct Conversion Transceiver
Features
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.
