SMV1705 Series

Hyperabrupt Junction Tuning Varactors

The SMV1705 group of silicon hyperabrupt junction varactor diodes is specifically designed for battery operation. The specified high capacitance ratio and low reverse voltage of these varactors make them appropriate for low-noise Voltage Controlled Oscillators (VCOs) used at frequencies in wireless systems up to and above 10 GHz.

SMV1705 Series includes SMV1705-004LF and SMV1705-079LF.

Please note: SMV1705-040LF is being discontinued and is not recommended for new designs.
