Product Detail

Si Hyperabrupt Diode in Plastic
MACOM’s MAVR-000400 series are ion-implanted, hyperabrupt junction, silicon tuning varactors in the SOT-23 surface mount package. These thermal oxide passivated diodes feature high capacitance ratio and quality factor. They are well suited for octave bandwidth tuning in the HF to UHF frequency bands. The standard capacitance tolerance is ± 10%, with tighter tolerances available. Capacitance matching at one or more bias voltages is also available. These diodes are supplied with 100% matte Sn plating. The MAVR-000400 series tuning varactors are useful for octave bandwidth tuning applications in the HF through UHF ranges. Applications include VCOs and voltage tuned filters in radios, cable TV tuners and test instruments where low cost and excellent lot-to-lot repeatability are critical. Linear tuning performance is available from 3 to 8 volts.
