SMV1770-040LF

Hyperabrupt Junction Tuning Varactors


Please note: SMV1770-040LF is being discontinued and is not recommended for new designs. The suggested replacement is SMV1270-079LF



The SMV1770-040LF 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 phase noise voltage-controlled oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz.
