Hyperabrupt Junction Tuning Varactors
SMV1129 and SMV1139
Features
I High Q
I Low Series Resistance for Low Phase
Noise
I Multiple Packages SOD-323, SC-79
and SC-70
I Designed for High Volume Commercial

I SPICE Models are Available
Description
The SMV1129 and SMV1139 silicon hyperabrupt junction
varactor diodes are designed for use in VCOs requiring
low resistance. The low resistance of these varactors
makes them appropriate for high Q resonators in
wireless system VCOs to frequencies beyond 2.5 GHz.
