MAVR-0000xx Series Surface Mount Hyperabrupt Wide-Band Tuning Varactors Rev. V8 Features SOT-23 (ODS-287) Low Cost Very High Capacitance Ratio from 1 to 8 Volts Surface Mount Package High Quality Factor Useful for Battery Applications SPC Monitored Ion Implantation for Excellent C-V Repeatability Available in Tape and Reel Lead-Free RoHS* Compliant Description The MAVR-000079 - 83 series of silicon hyperabrupt junction tuning varactors is produced with ion implantation and advanced epitaxial growth techniques. These diodes have thermal oxide passivation, and feature very high capacitance ratio and quality factor. They are well suited for use from the sub-HF through UHF frequency range. The single common cathode standard capacitance tolerance is 10%, with tighter tolerances available. Capacitance matching at one or more bias voltages is also available. These diodes are offered with standard Sn/Pb plating, as well as 100% matte Sn plating. Ordering Information Applications Part Number Single Configuration This series of hyperabrupt junction tuning varactors is suggested for usage where a large frequency MAVR-000079-0287FT tape and reel change is required with only a small change in tuning voltage. This series is appropriate for usage in wide band voltage controlled oscillators and MAVR-000080-0287AT tape and reel voltage controlled filters which require the largest rate of change of capacitance with voltage. The MAVR-000081-0287AT tape and reel large change in capacitance from 1 to 8 volts makes them very attractive for battery operated or other MAVR-000082-0287AT tape and reel systems with limited available control voltage. This varactor series can be used in VCOs and VTFs MAVR-000083-0287AT tape and reel from approximately 100 KHz through the UHF frequency band. 11 1 M/A-COM Technology Solutions Inc.
