Overview
Hyperabrupt Junction Tuning Varactors SMV1142–SMV1148 Features s Frequency Linear Design s Low Series Resistance s Available in the SOD-323 and SC-79 Packages s Designed for High Volume Commercial Applications s SPICE Models are Available Description 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.
