With a tuning range from 0.5V to 2.5V, the ZV950 series of hyperabrupt varactor diodes meets the requirements of 3V frequency control and filtering systems. The diodes are reported to be characterized ...
Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.
Designed for low-voltage systems that require a locally generated high-voltage output – such as an avalanche-photodiode, PIN-diode or for varactor-diode biasing – Maxim's MAX15032 low-noise step-up ...
