A coaxial connector, also known as an RF connector or coaxial jack, is an electrical connector used to pass radio frequency and low-frequency signals between two points using the same coaxial cable. The most common type of connector is the 1274043-1, a single-hole, three-level jack. This type of connector is an important part of the RF transceiver system and has many applications in both civil and military communication technology.

The 1274043-1 is composed of a three-level crossover port (mating port) and a three-level mating port set on the mating device. The three-level crossover port has a bottomcontact (ground), middle-contact (signal) and topcontact (shield) in order from top to bottom. The three-level mating port has an upper-contact, middle-contact, and a lower-contact that are connected to the coaxial cable’s center conductor, outer conductor, and shield in order from top to bottom. The shield of the coaxial cable is then connected to a mating device such as an RF transceiver or another type of device.

In most applications, the 1274043-1 coaxial connector is used in a singlemating port pair configuration. This type of configuration uses only one mating port set to allow for one set of contacts to be used in a single RF transceiver system. The configuration consists of two mating ports, either on the same PCB or in a separate housing, connected to each other via a short coaxial cable. When the two mating ports are connected, signals pass through both ports. The signal going in one port will pass through the other port, creating an oscillating wave. This ensures that the signal in one port is the same as the signal in the other port, creating an ideal conduit for RF signals.

The working principle of the 1274043-1 connector is simple and straightforward. The threelevel mating port consists of three contacts, with the bottomcontact being the ground, the middle-contact being the signal, and the topcontact being the shield. The signal from the RF transceiver is transmitted through the signal contact while the ground establishes a reference and ensures that the signal is transmitted properly. The shield helps to reduce interference and provides additional power to the signal.

The 1274043-1 connector is a very versatile and useful tool for RF transceivers, allowing for signal transmission between multiple electronic devices. This type of connector is commonly used in civil and military communication technology and is an integral part of the RF transceiver system. The working principle of the 1274043-1 is simple and allows for a secure connection between devices. With its versatility and ease of use, the 1274043-1 is a great choice for a variety of applications.
