Description  
Maximum Ratings  
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.

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.  
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.  
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.  
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.
