Coaxial connectors (RF) are a kind of interface device used in electronic circuits to connect two pieces of coaxial cable. The 3-221185-1 is a kind of connector commonly used in the radio frequency (RF) and coaxial networks that has an RF performance up to 6GHz.

The most developed version of the 3-221185-1 is the sub-Miniature version A (SMA) that is characterized by its smaller size and weight relative to other connector series, like the 3-1126-C, and its high RF performance. The 3-221185-1 connector is widely used in a variety of end products, ranging from mobile devices and consumer electronics to automotive and medical applications.

The 3-221185-1 connector has a resilient structure that is designed to withstand harsh environments. It is composed of a heavy shell, a dielectric material, an internal contact, an external contact and a cable clamp. The shell is designed to provide reliable strain relief and mechanical stability, while the dielectric material is used to reduce the characteristic impedance and provide a low-loss transmission line. The internal contact is typically made of beryllium copper or brass, and provides an electrical connection between the internal and external contacts.

The external contact is typically made of gold-plated or silver-plated nickel. It is designed to reduce the contact surface resistance of the connector and provide a reliable electrical connection. Finally, the cable clamp is designed to secure the cable to the connector and provide strain relief to the internal and external contact points.

The 3-221185-1 connector works by coupling the inner and outer conductor of the coaxial cable. The inner conductor of the cable is connected to the internal contact of the connector and the outer conductor of the cable is connected to the external contact. The inner and outer contact points are then connected by a coaxial cable and the RF signal is transferred from the internal contact to the external contact.

The 3-221185-1 connector is designed to provide a reliable connection between two coaxial cables. It is suitable for a wide range of applications, including RF, coaxial networks, mobile devices, consumer electronics, automotive and medical applications. It is characterized by its small size and weight, high RF performance, and resilient structure designed to withstand harsh environments.
