[email protected] where design meets manufacturing Since 2001 A1 Microwave’s Filter division has brought high quality technically advanced microwave filtering products to the Satcom, Radar and Fixed Link communications markets.. Fast delivery and No NRE (on standard designs) is achieved by using sophisticated in-house design and simulation software, all new designs are "right first time" allowing the design to move from the design computer to the machine shop without the need for prototyping. With in house CNC machining, turning, brazing, hard and soft soldering and bending facilities A1 Microwave can design or build to print a complete range of custom waveguide components and assemblies.

[email protected] where design meets manufacturing A1 Microwave’s Waveguide division has 22 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. WR90, R100, WG16 >
Antenna Feed Assemblies One of JMD Technologies specialities is to build difficult and complex Antenna and Feed Assemblies
‘S’ Band and ‘X’ Band feed with four integral antennas. This complicated assembly uses numerous ‘E’ and ‘H’ Bends, Tees and OMTs in WG10 and WG16 < v
WR284, R32, WG10 Portable radar switched antenna feed >
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
WR284, R32, WG10 Airport radar >
Slotted Array Waveguide Feeds
Feeds J Hook feeds Slotted waveguide feeds Feed horns Corrugated feeds ‘J’ Hook Feeds
