Product description:

SMA viết tắt của subminiature A được phát triển từ những năm 1960. Đầu nối sử dụng cho giao diện luồng, trở kháng 50 Ω cho dải tần lên đến 18 GHz.  Đầu nối hiệu suất cao kích thước nhỏ gọn độ bền vượt trội.

 

Dùng trong thiết bị radar pha mảng, hệ thống hạ cánh ILS và thiết bị khác, SMA connector cho cáp đồng trục SMA Plug-to-Jack cung cấp giao diện chính xác và đơn giản cho thiết bị vi sóng. Phù hợp với tiêu chuẩn quân sự MIL-C-39012 CECC 22110/111.

 

 Tính năng và lợi ích
      - Băng thông lên đến 18 GHz với đầu nối bằng thép không gỉ và ¼ - 36 khớp nối ren hiệu suất cao với thiết kế nhỏ gọn.

 

-          Sản phẩm thương mại (Brass SMA) mạ niken hoặc mạ vàng, với 250 chu kỳ tháo lắp.

 

-          Available for .085" and .141" diameter semi-rigid cables and all the standard flexible cables including double shielded RG-316.

 

-          Phase Adjustable SMA connectors provide ease of mechanical screw adjustments, compared to the delays and expense of laborious cable-trimming.
