DATA SHEET SMV1129-079LF: Hyperabrupt Junction Tuning Varactor Applications Low phase noise VCOs High-Q tuning elements in wireless system LOs Features High-Q Low series resistance for low phase noise Package is rated MSL1, 260 °C per JEDEC J-STD-020 Description Skyworks GreenTM products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks Definition of GreenTM, document number SQ04–0074. The SMV1129-079LF silicon hyperabrupt junction varactor is designed for use in low phase noise voltage controlled oscillators (VCOs) that require low series resistance tuning diodes. The low series resistance of the varactor makes it appropriate for use within tunable high-Q resonant circuits in wireless system local oscillators (LOs) to frequencies beyond 2.5 GHz. Table 1 describes the package and marking of the SMV1129-079LF varactor. Table 1. Packaging and Marking Single SC-79 Green™ SMV1129-079LF Marking: Cathode and SH LS = 0.7 nH The Pb-free symbol or “LF” in the part number denotes a lead-free, RoHScompliant package unless otherwise noted as Green™. Tin/lead (Sn/Pb) packaging is not recommended for new designs.

Electrical specifications are provided in Table 3. Figure 1 shows the typical performance of capacitance versus reverse voltage for the SMV1129-079LF, and Table 4 summarizes the capacitance for reverse voltages between 0 and 12 V. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SMV1129-079LF is rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. It can be used for lead or lead-free soldering. For additional information, refer to the Skyworks Application Note, Solder Reflow Information, document number 200164. The SPICE model for the SMV1129-079LF is shown in Figure 2 and the associated model parameters are provided in Table 5. Package dimensions are shown in Figure 3. Tape and reel dimensions are shown in Figure 4. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. Production quantities of this product are shipped in a standard tape and reel format. Table 2. SMV1129-079LF Absolute Maximum Ratings (Note 1) Parameter Symbol Reverse voltage (IR = 10 μA) Minimum Typical Maximum Units 12 V VR Reverse current (VR = 10 V) IR 20 nA Power dissipation PDIS 250 mW Forward current IF 20 mA Operating temperature TOP –55 +125 C Storage temperature TSTG –55 +150 C Electrostatic discharge: ESD < 250 V Human Body Model (HBM), Class 0 Note 1: 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.
