DATA SHEET SMV1801-079LF: Hyperabrupt Junction Tuning Varactor Applications VHF TV tuners VCOs Features Cross to NXP’s BB182 Low series resistance High capacitance ratio Ultra-small SC-79 package (MSL1, 260 °C per JEDEC J-STD-020) 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. Description The SMV1801-079LF is a silicon hyperabrupt junction varactor diode specifically designed for battery operation. The specified high capacitance ratio and low series resistance 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. Applications for the SMV1801-079LF include low-noise and wideband UHF and VHF VCOs for GSM, PCS, CDMA, and analog phones. Table 1 describes the package and marking of the SMV1801-079LF varactor. Table 1. Packaging and Marking Single SC-79 Green™ SMV1801-079LF Marking: Cathode and YS 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. Typical capacitance values are listed in Table 4. The relationship between capacitance and reverse voltage is illustrated in Figure 1. 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 SPICE model for the SMV1801-079LF varactor is shown in Figure 2 and the associated model parameters are provided in Table 5. The SMV1801-079LF varactor 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. Package dimensions are shown in Figure 3, and tape and reel dimensions are provided 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.

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.
