Coaxial connectors are a type of electrical connector used mainly in the radio frequency (RF) spectrum. This type of connector is designed to withstand the environment and retain a reliable electrical connection with a minimum of reflection and impedance. The BJ157FFL-2C is a coaxial connector used in a variety of applications to provide reliable electrical transmission of radio frequency signals.

Overview

The BJ157FFL-2C is a two-piece, solderless coaxial connector. It features a snap-lock coupling mechanism, for easy connection and disconnection, and provides RF shielding up to 6GHz. The outer dimensions are as follows: 3.65mm x 14.4mm. The inner conductor’s diameter is 2mm. The BJ157FFL-2C is typically used for SMT and through-hole type applications. It is available in black, red, gold, or white.

Construction and materials

The BJ157FFL-2C has a contact pin made of brass and an insulator made of teflon. The insulator is designed to ensure consistent and reliable performance in even the most demanding RF applications. The outer body is made of alloy to ensure high RF shielding. The coupling nut is made of a high strength metal alloy to guarantee a secure and reliable connection.

Insertion loss and return loss

The BJ157FFL-2C has an insertion loss of 3dB and a return loss of better than 15dB at frequencies from DC to 6GHz. This ensures reliable transmission of RF signals with minimal reflections or impedance.

Advantages

Among the advantages of the BJ157FFL-2C is its cost-effectiveness. It is a budget-friendly option, yet can still provide reliable performance up to 6GHz. It is also easy to install and is compatible with a variety of radio frequency products. The two-piece construction also eliminates the need for soldering, making it ideal for many applications.

Applications

The BJ157FFL-2C is widely used in a variety of applications, such as satellite broadcasting, cellular networks, and military communications. They are also used in some commercial radio applications, such as AM/FM radios, amateur radios and radar systems. They can also be used in audio applications, such as car stereos and home theater systems.

Working Principle

The BJ157FFL-2C works by forming an RF-shielded connection between two pieces of coaxial cable. The two pieces of coaxial cable are connected by a snap-lock coupling mechanism, ensuring a secure and reliable connection without soldering. The RF shielding is then provided by the alloy body of the connector, which prevents interference and reflections from entering the signal. The brass contact pin ensures reliable electrical transfer with minimal impedance and insertion loss. This allows for the transmission of RF signals with minimal interference or reflections, providing a reliable connection with optimal performance.
