Since 2001 A1 Microwave has brought high quality technically advanced microwave filtering products to the SATCOM market.
Using sophisticated in-house design and simulation software, all new designs are "right first time" allowing the design to move from the
computer to the machine shop without the need for prototyping.
A1 Microwave's expertise is firmly rooted in the design and testing of microwave products and our founder has over 25 years experience in
this area.
