Product Description

Product Overview

The Skyworks SMV1405 to SMV1430 series are silicon abrupt junction varactor diodes designed for Voltage Controlled Oscillators (VCOs) in wireless systems. These diodes offer high Q and low series resistance, contributing to low phase noise in high-Q resonators for applications up to 10 GHz. They are characterized for capacitance over temperature and are available in various plastic packages rated MSL1, 260 C per JEDEC J-STD-020.
