Đầu nối SMA, RP-SMA, SMB/SMC/SMS, SMP, MCX, MMCX, QLS, SSMB connector
Bạn đánh giá: 4 / 5
Dùng trong thiết bị radar pha mảng, hệ thống hạ cánh ILS và thiết bị khác, SMA connector cho cáp đồng trục và 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 và 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.
