SMV2025 Series

Surface Mount, Silicon Hyperabrupt Tuning Varactor Diodes

The SMV2025 series are silicon surface mount, hyperabrupt tuning varactor diodes, excellent for use as high-Q tuning elements in an RF Voltage Controlled Oscillator (VCO), voltage-controlled phase shifter, or tunable bandpass filter.

The minimum capacitance ratio from 2 V to 10 V is 2.2 makes the SMV2025 series suitable for wide bandwidth VCOs and wide phase range phase shifters.

The SMV2025 is manufactured in a surface mount, industry-standard SC-79 package and an ultra-small SOD-882 package that offer very low parasitic inductance and capacitance.
