Features

The Intersil ISL3684 Wireless LAN

Integrated RF Front End is part the

PRISM 3, 2.4HGz 11Mbit, 802.11b

• Highly integrated RF to baseband solution

• Frequency of operation . . . . . . . . . . . . 2.4GHz to 2.5GHz

• Low supply operation . . . . . . . . . . . . . . . . . . . 2.7V to 3.3V

• Noise figure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5.4dB

• Voltage gain . . . . . . . . . . . . . . . . . . . . . . -2.5dB to 88.5dB

• Gain and phase balance. . . . . . . . . . . . . . . . ±0.5dB, ±2deg.

• TX/RX switching speed . . . . . . . . . . . . . . . . . . . . . . . <1µs

• Direct simple interface to ISL3871

compliant radio chipset. The

ISL3684 interfaces directly with Intersil's ISL3871 Integrated

LAN Medium Access Controller with Baseband Processor.

The addition of the ISL3984 Power Amplifier and ISL3084

5GHz VCO completes the PRISM 3 LAN radio application.
