DATA SHEET SMV09 to SMV03 Series: Hermetic Ceramic Packaged Silicon Hyperabrupt Junction Varactors Applications VCOs Features High Q for low-loss resonators Low leakage current High tuning ratio for wideband VCOs SPICE model parameters Description The Isolink silicon hyperabrupt junction varactor diodes are processed using established ion-implantation technology resulting in low series resistance, wide tuning ratio devices with high Q values. These diodes are available in ceramic packages. The planar devices are fully passivated, which results in low leakage current and high reliability. The absolute maximum ratings of the SMV09 to SMV03 varactors are provided in Table. Electrical specifications are specified in Table. Typical capacitance values are listed in Table 3. The SPICE model is shown in Figure. SPICE parameters are listed in Table 4. Typical performance characteristics are provided in Figures and 3. 035C Isolink Proprietary Information Products and Product Information are Subject to Change Without Notice. July 0, 07
Table. SMV09 to SMV03 Absolute Maximum Ratings Parameter Symbol Min Typ Max Units Power dissipation PDIS 50 mw Reverse voltage VR V Forward current IF 00 ma Operating temperature TOP -55 +50 C Storage temperature TSTG -65 +00 C Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. ESD HANDLING: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times. Table.
