Specifications

The SMV1249-996LF offers a high tuning ratio, allowing for a significant change in capacitance with a small change in voltage. The low series resistance minimizes losses and improves circuit performance. The high Q-factor ensures low phase noise in VCO applications. The diode is designed for operation in the VHF and UHF frequency ranges. The capacitance range typically spans a few picofarads, and the tuning voltage range is typically a few volts. The package is a small surface-mount package, suitable for high-density board layouts.
