PRELIMINARY

ISL3092

11GHz VCO

The ISL3092 is a 11GHz SiGe

monolithic VCO circuit designed to

simplify and reduce the cost and size

of miniature wireless transceivers.

A fully integrated VCO requiring no external elements such

as inductors or varactors greatly simplifies low cost local

oscillator synthesized applications.

Included in this differential design is a high/low band

selection and a low-power standby function.

The ISL3092 directly interfaces with Intersil’s 2.4/5GHz

dualband ZIF (zero IF) converter (ISL3692). The addition of

the Intersil’s Wireless LAN Media Access Controller and

Baseband Processor (ISL3886) and Intersil’s Power

Amplifier (ISL3992) completes a worldwide wirelessLAN

radio application targeting both the 802.11b/g 2.4GHz and

802.11a 5GHz standard.

The ISL3092 is housed in a 16 lead Quad Flat No Lead

Plastic (QFN) Package suitable for Mini-PCI and PCMCIA

applications.
