Product Description
SMA CONNECTOR SERIES
Using a threaded interface, SMA 50 Ohm connectors are semi-precision units that provide excellent electrical performance from DC to 6GHz and outstanding mechanical durability. SMA connectors feature stainless steel or brass construction and ¼ - 36 threaded coupling, which offers high performance in a compact design.
For phase array radar, test equipment, ILS landing systems and other instrumentation using phase matching techniques, SMA interconnects offer a precise and simple means of phase adjustment for microwave devices. Built in accordance with MIL-C-39012 and CECC 22110/111, SMA connectors can be mated with all connectors that meet these specification mating diameters regardless of manufacturer.
FEATURES AND BENEFITS
- Light weight, compact and vibration proof design
- Low cost commercial grade (Brass SMA) available in nickel or gold plating
- Terminates to all standard flexible coaxial cables, low-loss (LMR) type cables and industry standard semi-rigid and conformable cables
APPLICATIONS
- Base stations
- Antennas
- Telecommunications
- Instrumentation
- PC/LAN
