SMA series radio frequency coaxial connector is a small radio frequency coaxial connector with screw connection, characteristic impedance 50 ohm female, frequency range 0-18GHz. It is widely used in telecommunications, networks, wireless communications, testing and measuring instruments, microwave communications, aerospace and navigation, weapon systems, microwave measurement equipment and other fields. SMB connector is a small push-in radio frequency coaxial connector developed and produced according to MIL-C-39012 standard. The characteristic impedance is 50 ohm and 75 ohm, and the frequency range is 0-4GHz.
Many people do not know the specific difference between sma connector and smb connector, and even confuse the two when purchasing. In fact, there are three main differences between them.
1. Impedance
The impedance of the two connectors is different. The sma connector is only 50 ohms, and the smb connector should be selected when 75 ohm resistance is required.
2. Different shapes
Although the appearance of both sma and smb can be customized according to their own needs, in order to avoid confusion, they will deliberately avoid producing connectors of the same shape during production. Therefore, the appearance of the two will be different.
3. Different calibers
Because the connection method and interface structure are different, the caliber of sma and smb are different. Therefore, only the same model can be used for mutual matching. Different models need adapters.
TXGAsma connector has the advantages of small size, light weight, convenient use, fast insertion and removal, low line loss, wide frequency band, superior mechanical and electrical performance, and high reliability.
