Since 2001 A1 Microwave Ltd has brought high quality technically advanced microwave filtering products to the
SATCOM market.
Using sophisticated in-house design 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.
A1 Microwave’s JMD Technologies division has over 20 years expertise in high quality ‘built-to-print’
waveguide components and assemblies for the radar, medical and satcom’s markets.

A1 Microwave’s JMD Technologies division has 20 years expertise in high quality ‘built-to-print’
waveguide components and assemblies for the radar, medical and satcom’s markets.
From WG6 / WR650 to WG22 / WR28, we can bend, twist, form, machine, braze and weld waveguide
including but not limited to standard guide, thin wall, half height, double-ridged, flexi or flex-twist.
Antenna Feed Assemblies
One of JMD Technologies
specialities is to build difficult
and complex Antenna and
Feed Assemblies
These are often for operation
in harsh environments.
Currently we have
assemblies in continuous
daily operation in climates
that range from very hot /
humid / salt laden air to
arctic cold
