The SMA male connector is modified to fit specific device. Due to constraint space in the device, the contact pin is designed with a 48 degree angle for solding purpose. Besides, the SMA male connector is designed with 2 mounting holes which strengthen the fixation to prevent loosening from vibration. The performance is good through at least 6GHz.
QMA right angle jack PCB receptacle connector is a 50 ohm connector up to 6 GHz frequency. It usually provides a VSWR < 1.05 through 2 GHz frequency band with mating cycle more than 500 times. Same as SMA connector, center contact is ø1.27 mm. Other dimensions and plating can be tailored upon request.
