Description

The AA028N1-A2 is a broadband millimeterwave low
noise amplifier in a rugged surface mount package which
is compatible with high-volume solder installation. The
amplifier is designed for use in millimeterwave
communication and sensor systems as the receiver front­end or as a gain stage when high gain and low noise figure
are required.The robust ceramic surface mount package
provides excellent electrical performance and a high
degree of environmental protection for long-term reliability.
A single supply voltage simplifies bias requirements.All
amplifiers are screened at the operating frequencies prior
to shipment for guaranteed performance. Amplifier is
targeted for high-volume millimeterw av e 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
and DC 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 a good RF, DC, and ground
contact is maintained.
