AP640R5-A3

Patent Pending

Description

The AP640R5-A3 is a broadband millimeterwave single­pole double-throw (SPDT) switch in a rugged surface
mount package which is compatible with high-volume
solder installation. Based on PIN diode MMIC technology,
the switch is designed for use in millimeterwave
communication and sensor systems when low loss and
high linearity are required. Typical applications are
transmit/receive function for TDD systems or switching
between signal paths.The robust ceramic surface mount
package provides excellent electrical performance and a
high degree of environmental protection for long-term
reliability. All switches are screened at the operating
frequencies prior to shipment for guaranteed
performance. Switch is targeted for high-volume
broadband applications such as satellite and fixed wireless
systems.

Alpha-2™ Surface Mount Package
Handling and Mounting

Millimeterwave components require careful mounting
design to maintain optimal performance. Alpha-2™ surface
mount packages (patent pending) provide a rugged and
repeatable electrical connection using standard solder
techniques.

The -A3 package is one of several parts in the Alpha-2™
surface mount package family.

Handling

The -A3 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 -A3 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 un-plated alumina.
The lid seal is epoxy.

Mounting Design

The -A3 surface mount package is installed on top of a
printed circuit board on a specially designed footprint.

Mounting footprint geometry for the -A3 package will be
supplied by Alpha Industries in electronic formats or paper
drawing.

Mounting the Package

The -A3 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 a good RF, DC, and ground contact is
maintained.
