SMV1144-011
SMV1144-011 is Hyperabrupt Junction Tuning Varactors manufactured by Alpha Industries.
- Part of the SMV comparator family.
- Part of the SMV comparator family.
Features s Frequency Linear Design s Low Series Resistance s Available in the SOD-323 and SC-79 Packages s Designed for High Volume mercial 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 parison to a conventional hyperabrupt junction varactor. This family of varactors is characterized for capacitance and resistance over temperature. SPICE models are provided.
