DATA SHEET SMV123x Series: Hyperabrupt Junction Tuning Varactors Applications Low tuning voltage VCOs High-Q resonators in wireless system VCOs High-volume commercial systems Features High capacitance ratio Low series resistance for low phase noise Packages rated 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 SMV123x series of silicon hyperabrupt junction varactor diodes are designed for use in Voltage Controlled Oscillators (VCOs) with a low tuning voltage operation. The low resistance of these varactors makes them appropriate for high-Q resonators in wireless system VCOs to frequencies over 10 GHz. This family of varactors is characterized for capacitance and resistance over temperature. Table 1 describes the various packages and markings of the SMV123x varactors.

Electrical specifications are provided in Table 3. Typical capacitance values are listed in Table 4. Typical performance characteristics of the SMV123x varactors are illustrated in Figures 1 through 4. 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 SMV123x varactors is shown in Figure 5 and the associated model parameters are provided in Table 5. The SMV123x series varactors are rated to Moisture Sensitivity Level 1 (MSL1) at 260 C. They 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 Figures 6 to 14 (even numbers), and tape and reel dimensions are provided in Figures 7 to 15 (odd numbers). 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. SMV123x Absolute Maximum Ratings1 Parameter Symbol Minimum Maximum Units 15 V Reverse voltage VR Forward current IF 20 mA Power dissipation PDIS 250 mW Operating temperature TOP -55 +125 C Storage temperature TSTG -55 +150 C Electrostatic discharge: ESD 1000 V Human Body Model (HBM), Class 1B 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. ESD HANDLING: 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 when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.
