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 TM Skyworks Green products are compliant with all applicable legislation and are halogen-free. For additional information, refer to Skyworks TM Denition of Green , document number SQ040074. 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. Skyworks Solutions, Inc.
