SMA End Launch Connectors Amphenol RF SMA End Launch Connectors are ideal for use on semiconductor evaluation and demo boards and in space-limited applications. The connectors feature a gold-plated, brass body with an electrical performance from DC to 18GHz. They offer a durability of 500 mating cycles minimum. The connectors are available for varying PCB thicknesses and with either round post or flat-tab contacts. Amphenol RF SMA End Launch connectors are ideal for applications requiring a low VSWR over a wide frequency range. They are commonly used in high-frequency applications.
