DATA SHEET

SMV2019-SMV2023 Series: Hyperabrupt Junction Tuning

Varactors

Applications

Low phase noise VCOs in wireless systems

RF and microwave VCOs and phase shifters

Features

Low series resistance

High capacitance ratio at low reverse voltage

Packages rated MSL1, 260

°C per JEDEC J-STD-020

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances) compliant packaging.

Description

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.
