SMA connector Features & Benefits
| Broadband performance DC to 18 GHz with low reflection stainless steel construction and ? - 36 threaded coupling offers high performance in a compact design. | |
| Low cost Commercial Grade (Brass SMA) available in nickel or gold plating which provides approximately 30% cost reduction with 250 mating cycles. | |
| 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. |
