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.
