Types of MCX Connector:
 
MCX Male Connector for RG316 RG174 Crimp Type MCX-C-J1.5

By Gender

MCX connector are available in male (plug) and female (jack) configurations, distinguished by their center contacts.

 

Female/Jack MCX Connectors: The contact is a center receptacle that receives the male pin.


Male/Plug MCX Connectors: The contact is a center pin that inserts into the female receptacle.

By Mounting Method

The mounting method of an MCX connector depends on how it is attached to a device or cable.

Cable-Type MCX Connectors: These connectors are crimped or soldered onto coaxial cables. They provide a secure and reliable connection for transmitting signals along the cable.


Panel Mount MCX Connectors: Designed to be installed on equipment panels or enclosures. These typically have 2-hole flange or bulkhead design


PCB Mount MCX connectors: Soldered directly onto PCBs. There are available in surface-mount, edge-mount or through-hole configurations.

MCX Female Connector for RG316 RG174 Crimp Type MCX-C-K1.5
MCX Male Connector Right Angle for RG316 RG174 Crimp Type MCX-C-JW1.5

By Orientation

MCX connectors are available in straight or right-angle orientations to suit space and routing constraints.

 

Straight MCX Connectors：Ideal for linear cable routing and direct line connections.


Right Angle MCX Connectors：90° bend design is for space-saving layouts and help to manage cable routing effectively.

 

Features
 
 

The main features of an MCX connector include:

 

Small size:

Typically smaller than other RF connectors like SMA or BNC.

 
 

Snap-on coupling:

Allows quick and easy connection and disconnection.

 
 

Electrical performance:

Provides impedance of 50 Ohms and a frequency range of up to 6 GHz.

 
 

Durability:

Designed to withstand more than 500 mating cycles.

 

 

 
Advantages of MCX Connector
 
01/

Compact size saves space
The outer diameter of MCX connector is about 3.6mm, which is about 30% smaller than the common SMA connector. It is very suitable for space-constrained applications, such as smartphone modules, wearable devices, drones, GPS receivers and other devices with very high space requirements.

02/

Supports high frequency signals with stable performance.
The MCX connector supports frequency up to 6 GHz, providing good signal integrity and low VSWR. It can be applied to Wi-Fi, LTE, GNSS, satellite receivers and other wireless communication devices to ensure signal stability and distortion-free.

03/

Quick connect and disconnect design
The MCX connector adopts a snap on connection design. It allows tool-less assembly and disassembly. Greatly simplifying the testing and maintenance process. Ideal for test instruments, module test lines, and temporary connection equipment. It saves labor and time costs.

04/

Lightweight and sturdy structure
The MCX connector features a gold-plated or nickel-plated housing with excellent resistance to oxidation and corrosion. It keeps the connection stable even in harsh environments. It is very suitable for aerospace, military, outdoor surveillance and other demanding applications to ensure long-term reliability.

 

Applications of MCX Connectors
 

GPS receivers & navigation gear
Pop open a car GPS unit and you’ll usually spot an MCX female port waiting for an external antenna. Hikers who rely on handheld GPS units use it too, since an MCX-to-SMA adapter makes it easy to attach a high-gain antenna for better reception in remote areas.

 

DVB-T / Digital TV Tuners
Those tiny USB TV sticks that let you watch over-the-air broadcasts? Many ship with an MCX jack. Since most household antennas don’t use MCX, people often keep a little MCX-to-F or MCX-to-SMA adapter in the drawer to make it work.

 

Software-defined radios (SDRs)
Entry-level SDR kits, popular with amateur radio enthusiasts, rely on MCX because it’s compact and easy to swap. When you’re testing antennas across different frequency bands, being able to “snap on, snap off” without fumbling with threads is a real time-saver.

 

IoT and telemetry modules
Some IoT boards squeeze in an MCX connector to balance space savings with signal stability. It’s larger than U.FL, but far sturdier—useful in devices that get handled more often.

 

Lab & measurement equipment
Certain oscilloscopes, analyzers, and data acquisition cards integrate MCX connectors. For engineers, this offers a compact yet robust input without the bulk of SMA or BNC.

FAQ

 

 

Q: What exactly is an MCX connector?

A: It’s a miniature RF connector (about 3.6 mm in diameter) that uses a snap-on coupling instead of threads. You’ll commonly see it on GPS receivers, TV tuner dongles, SDR radios, and certain lab cards.

Q: How is MCX different from MMCX?

A: Size is the main difference. MCX is ~3.6 mm, while MMCX is only ~2.4 mm. They look similar but don’t fit together. In general, MCX shows up in GPS and DVB devices, while MMCX is more common in IoT boards and earphones.

Q: What about MCX vs SMB?

A: Think of SMB as the older, bigger cousin (~4.0 mm). MCX is about 30% smaller, lighter, and chosen when space is limited.

Q: Can I hook up an MCX port to an SMA antenna?

A: Yes, but you’ll need an MCX-to-SMA adapter or cable. This is a very common setup for GPS modules and SDR kits.

Q: Is MCX suitable for high-frequency or mmWave?

A: No. MCX is reliable up to about 6 GHz. For mmWave or very high-frequency testing, you’ll need connectors like SMA, 2.92 mm (K), or 2.4 mm.

Q: How many times can you plug/unplug an MCX before it wears out?

A: Most are rated for around 500 mating cycles. After that, the snap-on fit may loosen, and performance can drop.
