SMV1702: Hyperabrupt Junction Tuning Varactors
Features
Designed for high-volume, low-cost battery applications Low series resistance High capacitance ratio Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020 SOD-323 package Available in tape and reel packaging

Absolute Maximum Ratings
Characteristic Value 20 mA 250 mW -55 C to +150 C -55 C to +125 C Class 0 Forward current (IF) Power dissipation (PD) Storage temperature (TST) Operating temperature (TOP) ESD human body model
Description
The SMV1702 devices are silicon hyperabrupt junction varactor diodes specifically designed for battery operation. The specified high capacitance ratio and low RS of these varactors make them appropriate for low noise VCOs used at frequencies in wireless systems. Applications include low-noise and wideband UHF and VHF VCOs.
Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) 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 must be employed at all times.
