Description

The SMV1231–SMV1237 series of silicon hyperabrupt junction varactor diodes is designed for use in VCOs with low tuning voltage operation. The low resistance of these varactors makes them appropriate for high Q resonators in wireless system VCOs to frequencies beyond 2.5 GHz. The SMV1231–SMV1237 series is fully characterized for capacitance and resistance over temperature. SPICE model is provided.

Features

● High capacitance ratio

● Low series resistance for low phase noise

● Multiple packages SOT-23, SOD-323, SC-70 and SC-79

● Designed for high volume commercial applications

● Full characterization with SPICE models

SMV1231属于分立半导体产品 > 二极管 - 可变电容（变容器，可变电抗器）。美国思佳讯公司制造生产的SMV1231二极管 - 可变电容（变容器，可变电抗器）可变电容二极管可按照电子可变电容器用途进行生产和分类，并且广泛用于调谐和频率合成应用。虽然大多数二极管的结电容都随着所施加的反向偏压增加而减小，并且能够用作可变电容二极管，但专门作为此类器件销售的产品在生产和分类时特别考虑了这种用途。
