San-tron’s high performance 2.92 mm field replaceable RF connectorsCDM offers San-tron’s high performance 2.92 mm field replaceable RF connectors. They are mode free and deliver low VSWR performance through 40 GH. The 2.92 mm connectors are inter-mateable with SMA and 3.5 mm connectors. The pin of the 2.92 mm male connector is shorter than an SMA or 3.5 mm male pin so that the bodies of the male and female connectors engage before the pin and socket contacts. This mitigates wear from mating misalignment found with SMA or 3.5 mm connectors. The new 2.92 mm field replaceable connectors are available in 3/8- and 1/2-inch square, 2-hole .550” flange, and 2 hole .625” flange configurations for 0.009”, 0.012”, and 0.020” launch pin diameters. Other mounting options may be available upon request.

25-001-Q3-1-AH - N Type Solder Clamp Plug in white bronze from COAX ConnectorsAn RF connector, often referred to as a coax or coaxial connector, is an electrical connector designed to carry RF signals in a transmission line. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. RF connectors can also be mounted directly on a PCB to carry a signal to and from the tracks on the board, using a fastening mechanism such as thread, bayonet, or blind-mate, as seen on the  25-001-Q3-1-AH – N Type Solder Clamp Plug in white bronze from COAX Connectors. RF connectors also minimize the change in transmission line impedance at the point of connection in order to reduce signal reflection and power loss. By maintaining the shielding of the cable an RF connector will prevent external signals entering the circuit through electromagnetic and capacitive pickup. This allows the RF connector and cable to carry high frequency and high data-rate signals without interruption or degradation.

Rosenberger RF coaxial connectorsRosenberger carries a wide range of RF coaxial connectors. High-frequency connectors are used to connect printed circuit boards, cables and devices, enabling very high frequencies to be transmitted.  A consistent wave resistance (impedance)  maintained in the transmission system is crucial. The diversity ranges from miniature to large and even heavy connectors – these must always function reliably no matter how tough the conditions. Not only are the connectors essential for enabling existing and future technologies, they must be able to adapt to ecological and economic conditions, withstand ever-increasing transmission rates, and continually satisfy demands for performance and reliability. Such requirements apply across all sectors, whether communication, medicine, industry, automotive, consumer goods, or other high-tech applications.
