Description
The AA026P2-A4 is a broadband millimeterwave medium
power amplifier in a rugged surface mount package that
is compatible with high-volume solder installation. The
amplifier is designed for use in millimeterwave
communication and sensor systems as an output stage
or driver in the transmit chain or LO chain when high gain
and high linearity is required. The robust ceramic
surface mount package provides excellent electrical
performance and a high degree of environmental
protection for long-term reliability. All amplifiers are
screened at the operating frequencies prior to shipment
for guaranteed performance. Amplifier is targeted for highvolume millimeterwave applications such as point-to-point
and point-to-multipoint wireless communications systems.

Alpha-2TMSurface Mount Package
Handling and Mounting
Millimeterwave components require careful mounting
design to maintain optimal performance. The Alpha-2
TM
surface mount package (patent pending) provides a
rugged and repeatable electrical connection using
standard solder techniques.
The -A4 package is one of several parts in the Alpha-2
TM
surface mount package family.
Handling
The -A4 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 -A4 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 -A4 surface mount package is installed on top of a printed
circuit board on a specially designed footprint.
Mounting footprint geometry for the -A4 package will be
supplied by Alpha Industries in electronic format upon request.
Mounting the Package
The -A4 surface mount package is compatible with highvolume 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 good RF, DC and ground contact is maintained.
