Silicon tuning Varactors consist in hyperabrupt epitaxial devices. They incorporate a passive mesa technology. This family is designed for a low cost, from medium to high volume market. They may be supplied in tape and reel for automated pick and place assembly on surface mount circuit boards.
DH71000 series abrupt tuning Varactor is available in a large selection of capacitance range. They provide the highest Q factor (low reverse series resistance) for a 30 volts silicon device.
Typical applications include low noise narrow and moderate frequency bandwidth applications
(VCO mainly), from HF to Microwave frequencies (up to 3 GHz). Other applications are voltage tuned filters, phase shifters, delay line.
