SMV1142–SMV1148
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.
