Description
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), voltagecontrolled 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, industrystandard SC-79 package and an ultra-small SOD-882 package that offer very low parasitic inductance and capacitance.
