Is SMA and coax the same?
SMA and RP-SMA are so-called coaxial connectors and the standard for antenna connections. With a screwable coupling mechanism, they form the minimum interfaces for coaxial cables. They are now used in many different devices and applications in the high-frequency range.
What is RG316 cable used for?
RG316 coax cable can be used in direct burial, radiofrequency and telecommunications applications. Often used for the transmission of radio frequency signals, RG316 cable can also be used in wireless communication, broadcast and military equipment.
What is RG316 coaxial cable?
RG316/U designates a special form of coaxial cable. RG316/U has a small diameter (0.098″ nominal), is extremely flexible due to its stranded center conductor (helpful video tip), and has an FEP outer jacket that lends it an operating temperature of up to 200°C.
What is the difference between RG58 and RG316?
LMR-200 also replaces RG58 and has the same 0.195” OD as LMR-195 cable. The difference is that LMR-200 has a slightly thicker center conductor, allowing it to cut down on signal loss a bit better than LMR-195.
What AWG is RG316?
ALPHA WIRE Coaxial Cable, RG316, 25 AWG, 50 ohm, 100 ft, 30.48 m

Can you use SMA connectors instead of solder pads?
Soldering directly to the pads of the SMA connector instead of using SMA connectors should work fine electrically. The obvious problem is that the cable is no longer removable. If you’re fine with that, then go ahead. It would be good to have some mechanical strain relief if this has a chance of getting flexed.
What kind of coaxial cable do I need for a PCB?
I have a length of RG-316 single shield 50Ω coaxial cable carrying a 5.8 GHz signal that I need to connect to a PCB. While cheap relative to most coaxial connectors, SMA connectors are still quite expensive, take up space and are relatively heavy. The PCB was designed for side mount SMA connectors.
Can you hold the cable down over the solder joint?
However, you can do most anything you want back down the cable a bit from the solder joint and where the shield is still intact. Perhaps you can hold the cable down with cable ties or something further from the board. Excellent advice in comments and answer thus far. Especially, yes I agree, nothing over the soldered joint itself.
