NXP BB171 VHF variable capacitance diode Data Sheet

The NXP BB171 is a VHF variable capacitance diode designed for use in Voltage Controlled Oscillators (VCOs). It's encapsulated in a very small SMD plastic package and offers excellent linearity, a very small series resistance, and a high Cd(1V) to Cd(28V) ratio of 22. With a reverse voltage of up to 32V and a capacitance range of 2.48pF to 2.89pF, it's ideal for a wide range of applications.
