Who makes the best SMA antennas?

C&T RF Antennas Inc is an SMA antenna manufacturer, Wifi SMA, 4G SMA, 5G SMA, GPS SMA, GSM SMA, NB-IoT SMA, Lora SMA, Female SMA, and RPSMA antenna supplier in China.

What is an SMA antenna?

The SMA connector is a sub-miniature coaxial cable connector and it takes its name from the words Sub-Miniature A connector. It finds many applications for providing connectivity for RF assemblies within equipment where coaxial connections are required.

What is an SMA connector?

SMA connectors are suitable for applications in the microwave field in the frequency range of up to 26.5 GHz.

Applications such as telecommunication communications, networking, wireless communications as well as testing and measuring instruments.

It features a wide frequency band, excellent performance, high reliability, and long life.

What are the types of SMA connectors?

There are 4 different types of SMA connectors using gender combinations, where gender refers to the center pin and polarity refers to the rotational characteristics.

SMA type

SMA male center pin, female thread

SMA female center hole, external thread

RP-SMA connector type

RP-SMA male center hole, “male” female thread

RP-SMA female center pin, “female” male thread

SMA-type connectors are required on boards that require 50 Ohm impedance connections to external antennas (Bluetooth, Cellular, GPS, XBee, and Nordic).

However, some boards use SMA connectors of different genders and polarities. Therefore, we need to match different antennas according to the gender or polarity of the RF connector.

When to use antenna SMA connectors?

SMA connector is a widely used small threaded connection coaxial connector, it has a wide frequency band. Excellent performance. High reliability. SMA connectors are suitable for connecting RF cables or microstrip lines in the RF circuit of microwave equipment and digital communication systems.

All antennas, cables, or anything is connected to a potential fixing object using either a male nut or female thread design, and all fixing devices are used for the connection.

This is applicable to all C&T RF Antennas Inc products. So all of our antennas are available with SMA male or RP-SMA female connectors. All of our boards are available with SMA females or RP-SMA males.

When to use antenna SMA/Female SMA/RP-SMA connectors?

Cellular and GPS (700/800/900/1700/1800/1900/2100/2300/ 2500/2700MHz and 1.57542GHz respectively) usually use SMA’s standard. The SMA male type is used for antennas and SMA female type is used for modules.

Any 2.4GHz (Bluetooth, ZigBee, WiFi, and Nordic) pass-through usually uses the RP/Reverse Polarity standard. RP-SMA male is used on the antenna and RP-SMA female is used on the module.

In fact, we ignore the gender issue most of the time. If you have an RP-SMA board or module, you will need to match it to the appropriate SMA and RP-SMA antenna, etc.

Do I need SMA or RP-SMA?

If your gear has a Standard SMA-Female (SSF) connector on it, then your cable needs to have Standard-SMA-Male. If your gear has a Reverse Polarity SMA-Female (RSF) connector on it, then your cable needs to have RP-SMA-Male.

What is RP-SMA used for?

RP-SMA stands for “reverse polarity” (sometimes also referred to as reverse SMA or for short “R-SMA”). It is designed to prevent the unauthorized connection of an external antenna to increase the range. In an RP-SMA connector, the gender has been changed.

What are the SMA-type antennas?

The SMA-type antennas include SMA male antennas, SMA wifi antennas, SMA antenna 4G, GPS antenna SMA, SMA LTE antennas, SMA whip antennas, SMA GSM antennas, SMA Bluetooth antennas, 868mhz SMA antennas, 900 MHz SMA antennas, SMA 433mhz antennas, SMA dual-band antennas, etc.
