DATA SHEET SMV1470-004, SMV1470-004LF: Abrupt Junction Tuning Varactor Features High capacitance ratio Designed for high volume ● Available in tape and reel packaging ● Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C per JEDEC J-STD-020 ● ● Absolute Maximum Ratings Description Characteristic The SMV1470-004 is a dual silicon hyperabrupt junction varactor diode in a common cathode configuration. The specified high capacitance ratio and low RS of this varactor make it appropriate for low noise VCOs and VCXOs in wireless systems. Applications include low noise and wideband VCO and VCXO for GSM, PCS, CDMA and analog phones. Forward current (IF) Power dissipation (PD) Value 20 mA 250 mW Storage temperature (TST) -55 °C to +150 °C Operating temperature (TOP) -55 °C to +125 °C ESD human body model Class O 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, 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 must be employed at all times. Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • [email protected] • www.skyworksinc.com 200069 Rev.
