SMP Adapters
SMP Coaxial Adapters are compact, high-frequency RF interconnect components designed to provide reliable electrical connections in space-constrained electronic systems. Featuring a small form factor and push-on or snap-on mating mechanism, SMP adapters are suitable for applications requiring high-density packaging, dependable signal transmission, and efficient installation.
SRFS Teleinfra offers SMP Coaxial Adapters for RF and microwave applications, including communication equipment, aerospace electronics, defense systems, test instruments, and high-density interconnect assemblies. These adapters can be used to connect compatible SMP interfaces and integrate RF components into compact system architectures.
Their compact construction makes SMP adapters particularly useful in applications where conventional threaded RF connectors may require too much installation space or assembly time. Depending on the selected configuration, SMP adapters can support board-to-board connections, cable-to-equipment interfaces, and transitions between compatible RF connector types.
For the best performance, the adapter configuration should be selected according to connector gender, interface compatibility, impedance, operating frequency, power requirements, and environmental conditions.
What Are SMP Coaxial Adapters?
SMP Coaxial Adapters are miniature RF components that connect compatible SMP interfaces or provide transitions between SMP and other coaxial connector types. SMP stands for SubMiniature Push-on, referring to its compact interface and push-on mating mechanism.
These adapters are designed to maintain the continuity of the coaxial signal path while helping minimize reflections and transmission losses when used within their specified operating limits. Their small dimensions make them suitable for densely packed RF modules, microwave assemblies, and electronic systems with limited installation space.
SMP adapters are available in different configurations, including male-to-male, female-to-female, male-to-female, and connector-series transition types. The exact electrical performance depends on the adapter design, interface configuration, materials, and manufacturing tolerances.

Frequently Asked Questions
An SMP Coaxial Adapter is a compact RF component used to connect compatible SMP interfaces or transition between SMP and other RF connector series. It is commonly used in high-density, high-frequency electronic assemblies.
SMP stands for SubMiniature Push-on. The connector series uses a compact push-on mating interface designed for applications where space and quick assembly are important.
SMP RF adapters are commonly designed for 50-ohm systems. Always verify the impedance of the selected part before integrating it into an RF circuit.
The maximum frequency depends on the particular adapter. Selected SMP designs support frequencies up to 40 GHz, while other models have lower specified limits.
SMP bullet adapters are used to connect compatible SMP receptacles, particularly in blind-mate and board-to-board applications where the connected components may have limited alignment tolerance.
Yes. Suitable SMP adapter designs are used in radar, avionics, aerospace, defense, and other compact RF systems. Selection should account for environmental, mechanical, and electrical requirements.
Yes. SMP-to-SMA adapters are available in compatible configurations, allowing systems with SMP interfaces to connect to equipment using SMA interfaces. Frequency and performance ratings depend on the selected model.
SMPM is a smaller RF connector interface intended for very high-density packaging. SMP and SMPM are distinct interfaces, so an SMP-to-SMPM adapter must be specifically designed for the required transition.
Check the connector interface, gender, mating style, impedance, frequency range, return loss, insertion loss, power handling, mechanical dimensions, and environmental requirements. Confirm compatibility with the equipment or assembly.
