The AM028S1-A2 is a broadband millimeterwave mixer
in a rugged surface mount package that is compatible with
high volume solder installation. The single balanced down
converter mixer is designed for use in millimeterwave
communication and sensor systems as a frequency
conversion stage in the receiver 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 mixers are screened
at the operating frequencies prior to shipment for
guaranteed performance. Mixer is targeted for high volume
millimeterwave applications such as point-to-point and
point-to-multipoint wireless communications systems.

“Alpha Two” Surface Mount Package
Handling and Mounting
Millimeterwave components require careful mounting
design to maintain optimal performance. The Alpha Two
surface mount package (patent pending) provides a
rugged and repeatable electrical connection using
standard solder techniques.
64 Via Holes

RF
Handling
The Alpha Two surface mount package is very rugged.
However, due to ceramic’s brittle nature, one should
exercise care when handling with metal tools. Do not apply
heavy pressure to the lid. Vacuum tools may be used to
pick and place this part.
Only personnel trained in both ESD precautions and
handling precautions should be allowed to handle these
packages.
Package Construction
The Alpha Two surface mount package consists of a base
and a lid. The package base is ceramic with filled vias and
plated castellations. The package lid is unplated alumina.
The lid seal is epoxy.

Footprint Geometry for Alpha Two
Surface Mount Package (for AM028S1-A2 mixer only)
Mounting the Package
The Alpha Two surface mount package is compatible with
high-volume surface mount installation using solder. RF,
LO and IF connections are accomplished with metallized
edge castellations that hold solder fillets. Ground
connections are accomplished by both metallized edge
castellations and filled vias to the bottom of the package.
Care should be taken to ensure that there are no voids
or gaps in the solder so that good RF, LO, IF, and ground
contact is maintained.
The Alpha Two surface mount package is installed on top
of a printed circuit board on a specially designed footprint.
Mounting footprint geometry will be supplied by Alpha
Industries in electronic formats or paper drawing.
