Description

The ISL3687 is a highly integrated, SiGe, Half Duplex RF/IF Converter with integrated PLL Synthesizer and VCO IC device. It is part of the Intersil PRISM® V, 5GHz radio chipset.

The ISL3687 directly interfaces with Intersil's ISL3787 1.2GHz IF Converter with AGC and Synthesizer to allow operation with a single SAW filter for both Transmit and Receive functions. The addition of the Intersil's ISL3877 Wireless LAN Media Access Controller and Baseband Processor completes a Wireless LAN radio application for the 802.11a 5GHz standard.

The ISL3687 combines all the necessary RF front end functions into a QFN Package suitable for miniPCI and PCMCIA applications..
