Coaxial Connectors (RF)

A coaxial connector is an electrical connector designed to work with coaxial cables, which are a type of signal transmission line consisting of an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. The term “RF”, or radio frequency, refers to the frequency range at which the cable and connector are designed to operate. The PL155AC-303 is an example of an RF coaxial connector.

Application field

The PL155AC-303 is designed to be used in applications such as cellular base station systems, indoor and outdoor distributed antenna systems (DAS), microwave links and data links. It is designed to provide superior performance in a wide variety of RF environments and is built to withstand extreme temperatures, weather, shock and vibration.

The PL155AC-303 is an ideal choice for environments that experience extreme temperature changes, such as the outdoors or harsh industrial environments. It is also suitable for environments experiencing high levels of humidity, salt spray, dirt and dust. This robust connector also provides excellent performance in military, aviation, and marine applications.

Working Principle

The PL155AC-303 is an advanced RF coaxial connector designed to ensure superior signal integrity and repeatable performance under the most extreme conditions. It is a self-aligning, snap-on design that features a waterproof gasket to provide reliable environmental sealing and a unique design that eliminates the need for strain relief.

The PL155AC-303 features a highly conductive brass body, stamped dimpled contact and gold plated contact that deliver a low-loss and reliable connection. The specially designed spring contact provides reliable electrical connection and allows for up to 30 dB of return loss.

The PL155AC-303 is a high-performance, snap-on connector with a built-in strain relief that reduces the risk of dynamic failure. The connector\'s advanced design is optimized for reliable performance in extreme environments and can have a long life cycle of up to 500 insertion/removal cycles.
