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.

Product Attributes

  • Brand: Skyworks Solutions, Inc.
  • Compliance: Skyworks Green products are compliant with all applicable legislation and are halogen-free. RoHS-compliant packages available (Pb-free symbol or LF in part number).
  • Moisture Sensitivity Level: MSL1 at 260 C
  • Solder Compatibility: Suitable for lead or lead-free soldering.
