DATA SHEET
SMV1263 Series: Hyperabrupt Junction Tuning Varactors
Features
High capacitance ratio at low reverse voltage Designed for high-volume, low-cost battery applications Multiple packages: SC-79 and SC-70 Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 C per JEDEC J-STD-020 Available in tape and reel packaging

Description
The SMV1263 devices are silicon hyperabrupt junction varactor diodes specifically designed for 3 V platforms. The specified high capacitance ratio and low RS of these varactors make them attractive for low phase noise VCOs in wireless systems up to and beyond 2.5 GHz. Applications include low-noise and wideband UHF and VHF VCO for GSM, PCS, CDMA and analog phones.
Absolute Maximum Ratings
Characteristic Forward current (IF) Power dissipation (PD) Storage temperature (TST) Operating temperature (TOP) ESD human body model Value 20 mA 250 mW -55 C to +150 C -55 C to +125 C Class 1A
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
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.
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.
