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), 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.

series diodes.
