www.DataSheet4U.com ® ISL3084 Data Sheet May 2003 FN5042.3 5GHz VCO The ISL3084 is a 5GHz 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 and varactors greatly simplifies low cost local oscillator synthesized applications. Included in this differential design is a low-power standby function and a stable process and temperature biasing operation. The ISL3084 is housed in a 16 lead QFN package well-suited for PCMCIA and miniPCI board applications.
