Coaxial Connectors (RF) have been around since the early days of radio technology and have seen increasing use in an ever widening variety of applications. The SF2921-6920 is one of the latest coaxial connectors to hit the market. This compact connector is designed for high-frequency applications, up to 12 GHz, and provides excellent signal integrity with minimal insertion loss and return loss.

The SF2921-6920 connector operates on the principle of wave impedance-matching, which works by matching the electromagnetic characteristics of the two components connected together, thus making the connection as compatible as possible with the signals it is intended to transmit. To do this, the connector must maintain a 50 Ω impedance over its full operating frequency range. This is accomplished through the use of special shielding, gold-plated contacts, and an insulator with an appropriate dielectric coefficient.

The main uses for the SF2921-6920 are for interface in wireless communication systems such as LTE (Long Term Evolution), WiMax, and HSPA (High Speed Packet Access). These systems use the frequencies of 900 MHz to 6 GHz, so this connector is ideal for them as it provides excellent signal integrity in these applications. Additionally, this type of connector has been used in base stations, radars, satellite communications, and television broadcast systems.

The main advantage of the SF2921-6920 is its small size yet high performance. It is approximately 40% smaller than the N7993 or N4115 connectors, yet its insertion loss performance is comparable. This makes it an ideal choice for applications where space is at a premium. It also features a medium-sized central pin to reduce the chance of RF leaks, as well as specially designed threaded terminations for ease of installation.

The SF2921-6920 connector is also well-suited to high-power applications, up to 10 watts, as it is designed with a special high-temperature dielectric material between the pin and the center contact. This temperature-resistant material ensures that the connector can handle the increased power levels without any degradation in performance.

The SF2921-6920 connector is a versatile and dependable solution for many applications where coaxial connections are required. Its 50 Ω impedance provides excellent signal integrity, its small size and high power handling make it suitable for applications where space is limited, and its ease of installation makes it a practical choice for installations and repairs.
