Disconnect -type pad structure that SMA connector was switchoverred to microstrip line

The utility model provides a top layer ground connection solder connection that the switching pad structure of from the SMA connector to the microstrip line, microstrip line are located the top layer or the bottom signals layer of PCB board usually, and the central signal terminal and the microstrip line on the PCB board of SMA connector are connected, the ground terminal and the PCB board of SMA connector. A central signal terminal both ends for following the wiring pad that the central signal terminal of SMA connector is connected to the microstrip line comprises detached two parts, and these two pads of working a telephone switchboard weld the SMA connector to wherein the width of every wiring pad is greater than microstrip line trace width. Utilize the capacitive of the perception compensation wiring pad department of cylindric central signal terminal, optimized the switching performance from the SMA connector to the microstrip line, ensure signal transmission's stability and quality.
