Hyperabrupt Junction Tuning Varactors
SMV1142–SMV1148
Features
■ Frequency Linear Design
■ Low Series Resistance
■ Available in the SOD-323 and SC-79
Packages
■ Designed for High Volume Commercial
Applications
■ SPICE Models are Available
Description
Absolute Maximum Ratings
The SMV1142–SMV1148 series of silicon hyperabrupt
junction varactor diodes are specifically designed with an
increasing gamma vs. voltage characteristic. This
characteristic will result in improved VCO frequency-voltage
linearity, in comparison to a conventional hyperabrupt
junction varactor. This family of varactors is characterized
for capacitance and resistance over temperature. SPICE
models are provided.
