Connector Interfaces: Understanding SMA, SMP, SMPM, SMPS, and Their Use Cases

August 11, 2025

At SV Microwave, we supply a large range of connector interfaces, such as SMPM, SMPS, NanoRF, BMB, mmWave, and more. But today, let’s dive into SMA, SMP, SMPM, and SMPS connector interfaces and their use cases.

 

 

SMA

SMA Connector Interface

 

An SMA, or Subminiature Type A, is an RF coaxial connector interface that typically operates up to 18 GHz; however, SV offers high-performance options working up to 26.5 GHz. Using a threaded interface, SMAs are compact and have outstanding mechanical durability. Since they are built in accordance with MIL-PRF-39012 and CECC 22110/111, they can be mated with all connectors that meet these spec mating diameters, regardless of manufacturer. SMAs are commodity items and can be used in any RF applications, as well as inside and outside-the-box applications, due to their ability for environmental sealing.

 Barometric Pressure (Altitude) MIL-STD-202, Method 105, Condition C, 70k Ft.

 

 

SMP

SMP Connector Interface

 

SV Microwave offers a complete line of SMP, or Subminiature Push-on, connector interfaces that conform to DSCC 94007, 94008, and MIL-STD-348. The SMP connector was developed to meet the industry’s need for a smaller, high-frequency, compact design. SMP incorporates ease of use and functionality. These are usually used in high-frequency compact applications. Additionally, SMP interfaces, as well as SMPM and SMPS, are used mostly for inside-the-box applications due to their lack of sealing at the interface. 

 

 Impedance (Ω) 50
 Frequency GHz 40 GHz
 Shielding Effectiveness ≥ -80 dB DC - 3 GHz
 ≥ -65 dB 3 - 26.5 GHz

 Barometric Pressure (Altitude) MIL-STD-202, Method 105, Condition C, 70k Ft.

 

 

SMPM

SMPM Connector Interface

 

SV Microwave offers a complete line of SMPM, or Subminiature Push-On Micro, connector interfaces. These connectors were developed to improve the application density and operating frequency range of the SMP connector, and are widely used in high-density, high-performance applications today.

 

 Impedance (Ω) 50

 Barometric Pressure (Altitude) MIL-STD-202, Method 105, Condition C, 70k Ft.

 

 

SMPS

SMPS Connector Interface

 

SV Microwave offers a complete line of SMPS, or Subminiature Push-On, Sub-Micro, connector interfaces. The SMPS connector utilizes the same great features as the SMP and SMPM connector series, but in an even smaller package. This series is ideal for applications where density is of great importance.

 

 Impedance (Ω) 50
 Frequency GHz 65 GHz
 Shielding Effectiveness ≥ -80 dB DC - 3 GHz
 ≥ -65 dB 3 - 26.5 GHz
