DATA SHEET
SMV1263 Series: Hyperabrupt Junction Tuning Varactors
Applications
Low-noise and wideband UHF and VHF VCOs High-volume, low-cost battery-powered tuning circuits
Features
High capacitance ratio at low reverse voltage Packages rated MSL1, 260 °C per JEDEC J-STD-020
Description
The SMV1263 series of silicon hyperabrupt junction varactor diodes are designed for 3 V platforms. The high capacitance ratio and low reverse voltage of these varactors make them attractive for low phase noise Voltage Controlled Oscillators (VCOs) in wireless systems up to and over 2.5 GHz. Table 1 describes the packages and markings of the SMV1263 series of varactors.
