GaAs, High Q Abrupt Tuning Varactors
Features
• Constant Gamma Abrupt Junction: 0.5
• Highest Q
• Large Capacitance Variation with Voltage
• Custom Tailored Designs Available on Request
Description
The MA46600 series of microwave tuning varactors is
afamily of abrupt junction gallium arsenide devices
featuring Q factors in excess of 8000. This series is
specifically designed for broadband high Q tuning per-
formance (up to 8000 at -4 volts and 50 MHz) from L
through Ka band. Characteristics such as high reliabil-
ity, low leakage and close capacitance tracking be-
tween diodes are typical of these devices. Standard
capacitance matching is ± 10%,but closer matching is
available upon request. All diode types are available
in a wide selection of ceramic packages as well as in
chip form.
Applications
The MA46600 series of tuning varactors can be used for
both broad and narrow band tuning through Ka-band.
Typical applications include solid state tuning of VCOs
using transistors or Gunns as well as voltage tunable
filters and amplifier circuits. The GaAs abrupt junction
tuning varactors offer the highest Q of any tuning varactors
and are utilized in high frequency applications where
Q is premium.
