Customization

➊ TECHNICAL PERFORMANCE

• Circular polarization available with external

hybrid coupler

• Uniform gain over operational bandwidth

•

Dual linear discrimination with high polarization

purity and isolation

• Low VSWR

• Wide bandwidth

➋ DESIGN

• Prevents excitation of unwanted higher order

modes in the aperture

• Smooth radiation pattern over the operational

bandwidth

• Lightweight for easy handling

➌ REPEATABILITY

• Stiff and robust mechanical design

•

Standard SATIMO circular interface for precision

centering

• Precision pin for accurate polarization alignment

• Precision machined

• High reliability connector
