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.
