The DIN 1.0/2.3 connector is an RF connector used for coaxial cable at microwave frequencies. They were introduced in the 1990s for telecommunication applications. They are available in 50 Ω and 75 Ω impedance and are compatible with the most widely used cable sizes. It has a push/pull lock and releases feature. The DIN 1.0/2.3 is ideally suited to applications where space limitation is a factor. In broadcasting applications, the 75 Ω version is used for Serial Digital Interface video data up to a maximum frequency of 4 GHz. The 50 Ω connector can be used to a maximum of 10 GHz.
