Surface-Mount, Silicon Hyperabrupt Tuning Varactor DiodesThe SMV2026 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 2.0, which makes the SMV2026 series suitable for wide bandwidth VCOs and wide phase- range phase shifters.
The SMV2026 is manufactured in a surface-mount, industrystandard SC-79 package and an ultrasmall SOD-882 package that offer very low parasitic inductance and capacitance.
SMV2026 series includes SMV2026-079LF and SMV2026-040LF.
- Low series resistance and leakage current for low phase-noise VCOs
- High-capacitance ratio: CT (2 V)/CT (10 V) = 2.0 minimum
- Broad 15-V tuning range
- Competitive cross to Toshiba 1SV179 varactor diode
- SC-79 and ultrasmall SOD-882 packages (MSL1, 260 °C per JEDEC J-STD-020)
