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.
