SMA-KE-P903 emale straight head (180 degrees) - external screw type 11.5 thread

SMA-KE-P902 products are a kind of coaxial connector with small threaded connection which are widely used. They adopt UK standard threaded connection for high strength and good shock resistance. The central conductor and insulator of the SMA series connectors are usually captured to obtain a sufficiently low VSWR. The end of the outer conductor contacts directly to minimize the insertion loss.

Product Description:

SMA series products are a kind of coaxial connector with small threaded connection which are widely used. They adopt UK standard threaded connection for high strength and good shock resistance. The central conductor and insulator of the SMA series connectors are usually captured to obtain a sufficiently low VSWR. The end of the outer conductor contacts directly to minimize the insertion loss.

Compared with other types of connectors, the SMA series connectors have the characteristics of small size and low VSWR. They will still have good electrical performance even at 18 Ghz, with appropriate cables; and these special processed SMA connector can be used up to 25Ghz.

SMA series products have long lifespan, superior performance and high reliability. They are widely used to connect radio frequency coaxial cable or microstrip in the radio frequency circuit of microwave devices and digital communication devices.

SMA?What is SMA?

The full name of SMA is Small A Type, also known as SMA connector or SMA interface. It is suitable for microwave applications in frequency range up to 26.5 GHz. SMA interface has wide bandwidth, excellent performance, high reliability and long lifespan. It is a radio frequency and microwave connector that is widely used in telecommunication, networking, wireless communication, detection and measurement instruments.


How should I recognize SMA Male and SMA Female heads? How to differ Male and Female needles?

There are many kinds of SMAs, one is called SMA, the other is RP-SMA.

The difference between them is:

The standard SMA is "inner thread + needle", "outer thread + hole"

1. Positive SMA Male head + Male needle (SMA-J, or SMA Male)

2. Positive SMA Female head + Female needle (SMA-K, or SMA Female)

RP-SMA is "inner thread + hole", "outer thread + needle "

3. Reverse SMA Male head + Female needle (RP-SMA-J or RP-SMA Male)

4. Reverse SMA Female head + Male needle (RP-SMA-K or RP-SMA Female)
