DATA SHEET SMV1770-040LF: Hyperabrupt Junction Tuning Varactor Applications Low-noise and wideband UHF and VHF VCOs High-volume, low-cost battery-powered tuning circuits Features Low series resistance High capacitance ratio Ultra-small SOD-882 package (MSL1, 260 C per JEDEC J-STD-020) TM Skyworks Green products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Description TM Denition of Green , document number The SMV1770-040LF is a silicon hyperabrupt junction varactor SQ040074. diode specifically designed for battery operation. The specified high capacitance ratio and low reverse voltage make this varactor appropriate for low phase noise voltage-controlled oscillators (VCOs) used at frequencies in wireless systems up to and above 2.5 GHz. Table 1 describes the package and marking of the SMV1770-040LF. Table 1. Packaging and Marking Single SOD-882 Green SMV1770-040LF Marking: ED1 LS = 0.45 nH The Pb-free symbol or LF in the part number denotes a lead-free, RoHS-compliant package unless otherwise noted as Green. Tin/lead (Sn/Pb) packaging is not recommended for new designs. Skyworks Solutions, Inc.

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.
