DATA SHEET SMV2019-SMV2023 Series: Hyperabrupt Junction Tuning Varactors Applications Low phase noise VCOs in wireless systems RF and microwave VCOs and phase shifters Features Low series resistance High capacitance ratio at low reverse voltage Packages rated MSL1, 260 C per JEDEC J-STD-020 Description The SMV2019-SMV2023 series are silicon hyperabrupt junction varactor diodes. The capacitance ratio and low series resistance of these varactors make them attractive for low phase noise Voltage-Controlled Oscillators (VCOs) in wireless systems. Table 1 describes the various packages and markings of the SMV2019-SMV2023 series of varactors. Table 1.

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.
