SMV1270-079LF

Hyperabrupt Junction Tuning Varactor

The SMV1270-079LF is a silicon hyperabrupt junction varactor diode specifically designed for battery operation. The specified high-capacitance ratio and low reverse voltage make this varactor appropriate for low-noise voltage-controlled oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz.
