Description
M/A-COM’s silicon hyperabrupt tuning varactors combine
advantages of a repeatable ion-implant process with
excellent passivation and low series resistance. The result-
ing diodes exhibit a C-V characteristic that is consistent
from lot to lot and stable within close tolerances, over
time and temperature.
Applications
The MA4ST520 series was developed for VCO tuning in
the VHF through UHF ranges. Applications are high
volume fixed tuned and frequency hopping military radios
where low cost and lot-to-lot C-V repeatability are critical.
The MA4ST530 family has a faster change of capacitance
with voltage.

Ordering Information
When ordering diodes, use the appropriate M/A-COM
model number and add case style suffix where appropri-
ate. (For example, MA4ST520B is an 18-22 pF (@ 4V)
varactor in the standard glass package (case style 4). The
MA4ST520B-132 is the unpackaged chip version.
