A range of silicon varactor diodes for use in frequency control and filtering. Featuring closely controlled CV characteristics and high Q. Low reverse current ensures very low phase noise performance. Available in single or dual common cathode format in a wide rage of miniature surface mount packages.
This document provides technical specifications for the Zetex 830 series of silicon 28V hyperabrupt varactor diodes. These devices are designed for use in frequency control and filtering applications, offering closely controlled capacitance-voltage (C-V) characteristics and high Q factors. The series includes various models such as the ZC829, ZDC833, ZMV829, ZMDC830, and ZV831, available in single or dual common cathode formats within miniature surface mount packages.
The datasheet details tuning characteristics, absolute maximum ratings, and electrical characteristics for different capacitance values ranging from 7.38 pF to 95.0 pF. It also includes package dimension drawings for SOT23, SOD323, and SOD523 packages, along with contact information for Zetex offices in the UK, Germany, USA, and Hong Kong.
