Tuning Varactors: MHV 500 Series
Microwave Hyperabrupt Tuning Varactors
Description
The MicroMetrics MHV 500 series
Microwave Hyperabrupt Tuning
Varactors are silicon epitaxial mesa
devices with high reliability glass
passivation which ensures optimum
VCO settling time and flat post tuning
drift response. They offer Q values
well above ion-implanted hyperabrupt
diodes. These diodes offer octave tun-
ing through 9 GHz. They are available
in a variety of case styles for surface
mount and/or cavity requirements.
Chip devices are recommended for
wide bandwidth performance and
frequency response.
Applications
The MHV 500 series linear Tuning
Varactors are used in VCO`s, filters,
amplifiers and modulators for wide
band tuning through K band. The
linear characteristics allow over one
octave linear tuning in suitable cir-
cuits. The combination of high Q and
low surface noise result in low FM
noise in VCO applications.
