ISL3090 Datasheet | Intersil

® Data Sheet June 2003 FN8045.1 .. 10GHz VCO The ISL3090 is a 10GHz Si Ge 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 ISL3090 directly interfaces with Intersil’s 2.4/5GHz dualband ZIF (zero IF) converter (ISL3690). The addition of the Intersil’s Wireless LAN Media Access Controller and Baseband Processor (ISL3890) and Intersil’s Power Amplifier (ISL3990) pletes a Wireless LAN radio application targeting both the 802.11b 2.4GHz and 802.11a 5GHz standard. The ISL3090 is housed in a 16 lead Quad Flat No Lead Plastic (QFN) Package suitable for Mini-PCI and PCMCIA applications.
