Features
Octave Frequency Tuning from 0 to 10 Volts
Good Linearity Tuning Ratio Without
Compensation Network
Offered in Package Styles Suitable for a Wide
Range of Applications
Alpha microwave hyperabrupt diodes are designed
for wideband tuning of microwave filters, resonators,
and local oscillators. Linear tuning, not possible with
conventional
abrupt–junction
tuning
diodes,
is
accomplished by maintaining an accurate silicon
doping profile using ion–implantation precision
control techniques.
This series of hyperabrupt diodes offer wide
bandwidth tuning with low bias voltage. For example,
a 22 volt hyperabrupt diode can provide the same
tuning variation as a 90 volt abrupt–junction diode.
Description
When capacitance and tuning ratio values are equal,
a hyperabrupt diode will have a Q (measured at –4
volts, 50 MHz) approximately 1/2 to 1/3 that of an
abrupt–junction diode.
These diodes are available in many Alpha ceramic
packages. They can be supplied in chip form or
mounted on a variety of packages. All chips are
passivated with silicon dioxide for reliability and low
leakage current.
The specifications table indicates chip capacitance
measured at 1 MHz. For packaged varactors add
appropriate package capacitance, e.g., 0.22 pF for
package 210, to obtain total capacitance.
