SMA Male RF Terminal Connector

SMA is an acronym for SubMiniature version A and was developed in the 1960's. It uses a threaded interface. 50 ΩSMA connectors are semi-precision, subminiature units that provide excellent electrical performance from DC to 18 GHz. These high-performance connectors are compact in size and mechanically have outstanding durability.

For phase array radar, test equipment, ILS landing systems and other instrumentation using phase matching techniques, these SMA connectors for semi-rigid coaxial cables and the SMA Plug-to-Jack adapter 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 spec mating diameters regardless of manufacturer.

SMA is available both in Standard and Reverse Polarity. Reverse polarity is a keying system accomplished with a reverse interface, and ensures that reverse polarity interface connectors do not mate with standard interface connectors. Amphenol accomplishes this by inserting female contacts into plugs and male contacts into jacks. Other manufacturers may use reverse threading to accomplish reverse polarity keying.

Features & Benefits

	Broadband performance DC to 18 GHz with low reflection stainless steel construction and ¼ - 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.

Applications

	Base Stations		Cable Assemblies		Components
	Instrumentation		Mil/Aero		PC/LAN
	Process Controls		Telecom
