DATA SHEET SMV1705 Series: Hyperabrupt Junction Tuning Varactors Applications x Low-noise and wideband UHF and VHF VCOs x High volume, low-cost batteries Features x Low series resistance x High capacitance ratio x Packages rated MSL1, 260 C per JEDEC J-STD-020 Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances) compliant packaging. Description The SMV1705 group of silicon hyperabrupt junction varactor diodes is specifically designed for battery operation. The specified high capacitance ratio and low reverse voltage of these varactors make them appropriate for low-noise Voltage Controlled Oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz. Table 1 describes the various packages and markings of the SMV1705 group of varactors. Table 1.

SMV1405-SMV1413 Series Absolute Maximum Ratings Parameter Symbol Minimum Typical Maximum Units 15 V Reverse voltage VR Forward current IF 20 mA Power dissipation PDIS 250 mW Operating temperature TOP -55 +125 qC Storage temperature TSTG -55 +150 qC Note: 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. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. The SMV1705 group of varactors are Class 0 Human Body Model (HBM) ESD devices. Table 3.
