What do you want to know about SMA connectors?

What is the difference between SMA and SMB connector ?

Difference	Picture	Dimension	Impedance	Frequency	Connecting Type	Advantage
SMA		Small	50 Ohm	0-18G (26.5G)	Screw	High frequency, Small size, Stable connection
SMB		Smaller	50 Ohm, 75 Ohm	0-4G	Push-on	Small volume, Easy to plug, Good at anti-vibration

Can we get a waterproof SMA female that the o-ring without protrude after tightening?

Generally our standard O-ring of SMA connector will protrude in the groove after tightening, which can meet the best performance on waterproof and anti-vibration. But if you have the special requirements, we’ll check the feasibility to ensure the custom available per your requirements. Just feel free to share your idea if you need adjusting the material, dimension, construction or package.

Besides SMA connector, can we get the SMA adapter or SMA cable extension?

Besides the SMA connector, we also offer SMA adapters and SMA cable extensions. We have various types available for selection. Please feel free to send us your new inquiry, including specific product descriptions, photos, and the quantity you require. This information will be very helpful for a quick confirmation of your order.

What is SMA connector used for?

Splitter

Amplifier

Antenna

Attenuator

SMA connectors find extensive application in the microwave domain, serving various purposes such as connecting coaxial cables to wave-guides and PCB micro-strips. Additionally, SMA connectors are prevalent in a range of components including sensors, amplifiers, attenuators, filters, combiner, crystal oscillators, and switches. Their versatility makes them indispensable in high-frequency circuits where precision and reliability are paramount
