SMV1430 Series

Plastic Packaged Abrupt Junction Tuning Varactors

The SMV1405-SMV1430 group of silicon abrupt junction varactor diodes is designed for use in Voltage Controlled Oscillators (VCOs) requiring tight capacitance tolerances. The low resistance of these varactors makes them appropriate for high-Q resonators in wireless system VCOs to frequencies above 10 GHz. This family of varactors is characterized for capacitance over temperature.

SMV1430 Series includes SMV1430-040LF.
