Description

The SMV1129 and SMV1139 silicon hyperabrupt junction varactor diodes are designed for use in VCOs requiring low resistance. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz.

Features

● High Q

● Low series resistance for low phase noise

● Available in SOD-323 and SC-79

● Designed for high-volume commercial applications

● SPICE models are available

● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020
