2. Please refer to application note M538 for surface mounting

instructions

M/A-COM’s MA4ST400 series are ion-implanted,

hyperabrupt junction, silicon tuning varactors in

the SOT-23 surface mount package. These ther-

mal oxide passivated diodes feature high capaci-

tance ratio and quality factor. They are well suited

for octave bandwidth tuning in the HF to UHF fre-

quency bands. The standard capacitance toler-

ance is ± 10%, with tighter tolerances available.

Capacitance matching at one or more bias volt-

ages is also available.These diodes are offered

with standard Sn/Pb plating, as well as with 100%

matte Sn plating on our RoHS compliant devices.

Applications

Single

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 tun-

ers and test instruments where low cost and ex-

cellent lot-to-lot repeatability are critical. Linear

tuning performance is available from 3 to 8 volts.
