Description
The AM028D1-A2 is a broadband millimeterwave mixer
in a rugged surface mount package which is compatible
with high volume solder installation. The double balanced
down converter mixer is designed for use in
millimeterwave communication and sensor systems as a
frequency converter in the receiver chain when wide
dynamic range and high isolation 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.
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.
Mounting Design
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.
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.
