GMV7821

GaAs Hyperabrupt Junction Varactor Diodes Features GMV7811, GMV7821 GMV9801, GMV9821, GMV9822 ■ Constant Gamma of 1.0 and 1.25 ■ Highly Linear Frequency Tuning ■ Constant Modulation Sensitivity ■ Lower Series Resistance and Higher Q in Comparison to Equivalent Silicon Hyperabrupt Varactors Flip Chip Chip Outline Drawings Description This series of GaAs hyperabrupt varactor diodes features a constant gamma of 1.0 and 1.25, which allows for a relatively linear frequency tuning for VCOs, modulators and tunable filters. Varactors in this series are grown by MBE (Molecular Beam Epitaxy), which allows monolayer control of the doping profile.This translates to superb waferto-wafer uniformity. The series resistance is lower, and Q is higher when compared to an equivalent silicon hyperabrupt varactor. These diodes are suited for applications at X band frequencies and above, where wide change in frequency is desired. However, in certain applications the GaAs hyperabrupt varactor exhibits a higher surface noise in comparison to an equivalent silicon varactor. 540-011 0.026 (0.66 mm) ± 0.001 (0.025 mm) 0.013 (0.33 mm) ± 0.001 (0.025 mm) 0.008 (0.20 mm) ± 0.001 (0.025 mm) 0.013 (0.33 mm) ± 0.001 (0.025 mm) 0.005 (0.13 mm) ± 0.001 (0.025 mm) 0.004 (0.10 mm) ± 0.001 (0.025 mm) MAX.
