Description
M/A-COM’s MA45400 series is a highly repeatable,
UHCVD/ion-implanted, abrupt silicon tuning varactor in a
cost effective surface mount package. This series of varac-
tors is designed for general purpose tuning in the HF to
UHF frequency bands. It is efficient for wide tuning across
a 0-30V range. These diodes are offered with standard Sn/
Pb plating , as well as 100% matte Sn plating on our RoHs
compliant equivalent devices.
Application
M/A-COM’s MA45400 series tuning varactor is useful for
tuning applications in the HF through UHF ranges. Appli-
cations include VCO’s and voltage tuned filters in radios,
cable TV tuners and test instruments where low cost and
excellent lot to lot repeatability are critical.
