Multiple Control InterfacesWe incorporate multiple interface options
from TTL and CMOS to RS-232, utilizing
EMI pins, D-Sub and Micro-D connectors.
Channelized ManifoldsSwitch manifolds are channelized to obtain
maximum channel-to-channel isolation.
Reverse and Over Voltage ProtectionOur switched filter banks use multiple protection
circuits including high performance Schottky diodes
to prevent damage in a harsh application environment.
| Loaded with Standard Features |
High Performance is not the only facet of API’s industry leading Switched Filter Banks. Another important element that sets us apart is features. Loaded with standard features, our proven designs are engineered for demanding performance in both high-end commercial applications as well as military markets.
| The Filter Specialists |
Versatility is a hallmark that separates API Technologies from other filter companies. Choosing from a wide assortment of topologies including lumped element, cavity, ceramic, SAW, tubular, suspended sub-strate, and waveguide our engineers match the optimum topology to your requirements. Unlike other filter companies, API continues to prove that by offering multiple options, a customer can weigh the benefits of: size vs. loss, rejection vs. size, selectivity vs. group delay...and select the perfect filter to optimize system performance and value.
Low Loss Tubular FiltersIn order to achieve the
lowest loss possible,
we choose to use
silver plating during
extreme Low Loss
applications.
High Quality Ceramic FiltersAlthough we can provide many standard finishes,
we prefer to use gold plating on our surface mount
packages offering better solderability, conductivity
and corrosion resistance than more common finishes.
Temperature CompensatedAPI Technologies has frequently
designed and manufactured cavity
filters with temperature drifts of
less than 1 ppm/°C.

Creative Lumped Element DesignsUtilizing sophisticated software such as
Sonnet EM Simulatore and SolidWorks,
creative layouts can be realized to optimize

Superior Group Delay SAW FiltersOur proprietary SAW filter design
technologies provide superior Group
Delay Matching Performance with
minimal signal distortion.
Suspended SubstrateIntegrating suspended substrate
topologies with lumped and
distributed elements provide
enhanced unloaded Q and
small size in one design.

| Superior Quality |
World Class QualityThe efficiencies gained from our manufacturing procedures enable us to produce small volume custom products and high run requirements. We also monitor critical phases of the production process with automated SPC data measurement tools.
Preventing ProblemsAPI Technologies utilizes the latest in systematic failure process controls including FMEA (Failure Mode & Effects Analysis) which is one of our primary risk mitigation tools and prevention strategies.
Close Process MonitoringWe monitor critical phases of the production process with proprietary data logging technology.
Examples of the kinds of quality techniques that our design engineers build into every filter include:
• Spring-loaded, self-locking tuning bushings
and rotors reducing the risk of metallic
slivers which can lead to premature failure
in cavity designs.
• Annealing of all inductors to remove any
metal stress memory for consistent and reliable
inductor performance.
• Designs incorporating smooth angles and
edges for superior plating adhesion and higher
operating power.
API Technologies promotes an environment where all of our employees are encouraged to suggest prod-uct improvements and identify any imperfections. Our employees continually strive to exceed the goals placed before them, knowing that our success is directly related to the satisfaction of our customers.
Our key manufacturing
facilities also incorporate
strategic disciplined processes
including APQP (Advanced
Product Quality Planning) to
ensure that a specific, structured
sequence of operations is
completed to prevent
potential quality problems.
LogisticsTeamwork is center stage with theAPI philosophy of conducting business. Every territory around the globe teams up an outside regional manager to aninside sales associate.
