Description
The AV850M2-A2 is a broadband millimeterwave voltage
variable attenuator in a rugged surface mount package
that is compatible with high-volume solder installation. The
attenuator is designed for use in millimeterwave
communication and sensor systems as a variable
attenuation stage in the receiver or transmitter chain when
wide dynamic range and high linearity are required. The
robust ceramic surface mount package provides excellent
electrical
performance
and
a
high
degree
of
environmental protection for long-term reliability. All
attenuators are screened at the operating frequencies prior
to shipment for guaranteed performance. Attenuator is
targeted for high-volume millimeterwave applications such
as point-to-point and point-to-multipoint wireless
communications systems. Control voltage VC2 sets the
attenuation level while VC1 adjusts return loss for the part.
