The SMA 905 adapter is a right-angle (90-degree) RF adapter that belongs to the SMA (SubMiniature version A) connector family and is designed for vertical connection of coaxial cables or devices in space-constrained scenarios. Its core function is to convert signal direction to avoid signal loss or mechanical damage caused by cable bending.
Structural features
Right-angle design:
The interface is bent at 90 degrees, suitable for small spaces (such as inside equipment and densely wired environments).
Interface type:
Male: with external thread and center pin (insertion type).
Female: with internal thread and center hole (receiving type).
Common combinations: male to female (Plug to Jack), female to male (Jack to Plug), etc.
Core functions
Signal switching: Transmit high-frequency signals (such as microwaves and millimeter waves) in radio frequency (RF) systems.
Space optimization: Reduce the size of the device and simplify the wiring complexity through right-angle design.
Impedance matching: Standard 50 Ω impedance, compatible with mainstream RF equipment (such as communication base stations and test instruments)
Typical application areas • Communication systems: 5G base stations, satellite antennas, WiFi routers. • Test and measurement: right-angle interface extensions for spectrum analyzers and network analyzers. • Aerospace: Compact connection solutions for airborne radars and navigation equipment. • Medical equipment: Precision signal transmission for MRI and radiofrequency therapy devices
Key parameters
Frequency range: Conventional adapters support DC~18 GHz (high-frequency performance depends on materials and processes).
Durability: High-quality products can withstand more than 500 plug-in and unplug cycles.
Temperature range: -65°C ~ +165°C (military-grade adapters can reach a wider range).
The core value of the SMA 905 adapter is to solve the space limitation problem through the right-angle structure while maintaining efficient transmission of high-frequency signals. It is an indispensable precision component in RF engineering and is widely used in communications, testing, military and other fields. When choosing, focus on frequency requirements, interface type and manufacturing process to ensure stable system performance.
