UHF HYPERABRUPT JUNCTION VARACTOR DIODES DESCRIPTION These hyperabrupt diodes offer higher Qs than their VHF counterparts, but have slightly lower capacitance ratios. They are excellent for octave tuning up to 800 MHz, for straight-line-frequency tuning between 3 and 8 volts of bias, and for exceptionally high Q values and good large signal capabilities when tuned between 9 and 20 volts, which extends their useful range to over 1 GHz. Closely matched sets are available as are the tight toler- ance types designated by the suffix A.
