Description
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances) compliant packaging.
The SMV2019, SMV2022, and SMV2023 series are silicon
hyperabrupt junction varactor diodes. The capacitance ratio and
low series resistance of these varactors make them attractive for
low phase noise Voltage-Controlled Oscillators (VCOs) in wireless
systems.
Table 1 describes the various packages and markings of the
SMV2019, SMV2022, and SMV2023 group of varactors.
