3.5 mm, 2.92 mm and SMA Connector Compatibility

Jul 9, 2017

Yes. SMA, 3.5mm, and 2.92mm (K) connectors all have similar mechanical characteristics which allows them to be mated to each other. However, because the dimensions of each connector are slightly different the connection is not ideal and does result in degraded electrical performance.The outer diameter of a SMA Connector is about 4.13 mm (0.163 in) and the outer diameter of the of the other two con...read more

JESD204 is a standardized serial interface used by data converters (ADCs and DACs) and logic devices (FPGAs or ASICs). This interface was developed by the JEDEC JESD204 standards committee to reduce the number of data inputs/outputs between high-speed data converters (ADCs and DACs) and logic devices (FPGAs or ASICs). Other advantages of this interface include a reduced PCB/package area and a simp...read more
