Silicon Hyperabrupt Tuning Varactors: Low Cost
The Aeroflex / Metelics Low Cost Hyperabrupts offer high Qs. These diodes are excellent for octave tuning up to 800 MHZ and for straight-line frequency tuning between 3 and 8 Volt of bias. They achieve high Q values when tuned between
9 and 20 volts.
- Low Inductance
- Wide Capacitance Swing
- High Q
- Superior Reproducibility
