Description

M/A-COM’s MA4ST400 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.

Applications

The MA4ST400 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.

Ordering Information

The model number indicated is for a single varactor. When

ordering diodes in common cathode pairs add suffix “CK.” For

example, MA4ST401CK specifies model number MA4ST401 in

common cathode pairs. To order parts on tape and reel add suffix

“T” to the end of the part number. i.e., MA4ST401CK-T.
