FILTERS FOR SPACE APPLICATIONS


API Technologies designs, manufactures and qualifies filter components and assemblies for use in defense and commercial satellite payloads. Space flight hardware is designed to meet the harshest of spacecraft launch vehicle profiles and operational spacecraft operating environments. Other functions such as power dividing and combining can also be added.

API Technologies space-product design team engineers product solutions for use in space exploration, DOD, commercial, LEO, MEO, GEO, and deep space.

Our featured areas of product expertise include:

Switch filter designs can be from 2 to 12 or more independent channels that can be switched, utilizing pin diode switch topology and TTL logic control. Our products are in operation in space, or currently being deployed into Satellite RF Payloads. API Technologies continues to add to our Space Heritage with new designs year after year. API is proud to have two facilities with MIL-PRF-38534 Class K – out of only 18 world-wide.

Seam sealing provides a very reliable hermetic seal while maintaining a stable environment.

We provide high quality, space qualified filters!

We perform 100% on-wafer probe testing for every SAW die.

We’ve developed and manufactured
multitudes of filter designs.

We incorporate a silicon based thermo-set resin which further dampens stray acoustic energy.

Designed and deployed into Space and MIL-STD uninhibited fighter environments.

We ensure that 100% of our SAW filters are pre-aged at 100°C.

Our team designs and manufactures
robust mechanical housings.

Cutting edge SAW technology for today’s military and commercial markets.

Transmit and receive channels are isolated by as much as 120dB channel to channel.

We use gold wires on all ball bonds.

Leaders in design & production of
custom filtering solutions.

Superior group delay performance of as low as 8 ns part to part.

We’ve qualified a significant number of new product designs for space flight.
