SMVA1470-004LF

Hyperabrupt Junction Tuning Varactor

The SMVA1470-004LF is a dual silicon, hyperabrupt junction varactor diode in a common cathode configuration. The specified high capacitance ratio and low series resistance make this varactor appropriate for low-noise voltage controlled oscillators (VCOs) and voltage-controlled crystal oscillators (VCXOs) in wireless systems for in-vehicle infotainment applications.
