SMA Cable Assemblies | RG174 / RG316 / LMR Jumpers | Industrial & Test Grades
Overview
Our SMA cable assemblies are manufactured in strict accordance with MIL-STD-348 standards, ensuring reliable RF performance across demanding applications. We offer two distinct grades to meet diverse requirements: Industrial Grade for robust field deployments and Test Grade for precision laboratory measurements.
Each assembly undergoes rigorous quality control including VSWR testing, insulation resistance verification, and mechanical durability assessment to guarantee consistent performance throughout its service life.
Two Grades Comparison
| Specification | Industrial Grade | Test Grade |
|---|---|---|
| Frequency Range | DC - 12.4 GHz | DC - 18 GHz |
| VSWR | < 1.25 | < 1.15 |
| Insertion Loss | < 0.8 dB/m @ 10 GHz | < 0.5 dB/m @ 10 GHz |
| Operating Temperature | -40°C to +85°C | -55°C to +125°C |
| Shielding Effectiveness | > 90 dB | > 100 dB |
| Applications | WISP, GPS, IoT Modules | Lab Testing, R&D, Calibration |
Cable & Connector Options
Common Connector Combinations
- SMA Male to SMA Female - Standard jumper configuration
- SMA Male to N Male - For connecting to larger RF systems
- SMA Male to BNC Female - Compatible with test equipment
Cable Types
RG174
Cost-effective solution for general purpose applications. Flexible and easy to route.
RG316
Enhanced shielding and lower loss. Ideal for critical signal paths.
LMR240
Low-loss coaxial cable for high-frequency applications up to 6 GHz.
Standard Lengths
Stock lengths available: 5cm, 15cm, 30cm, 50cm. Custom lengths available upon request with minimum order quantities.
Reverse Polarity SMA
Reverse Polarity SMA (RP-SMA) connectors feature reversed gender contacts compared to standard SMA connectors. The male RP-SMA has a center pin while the female has a socket, opposite to standard SMA configuration.
RP-SMA is commonly used in WiFi routers, wireless access points, and consumer wireless devices to prevent accidental connection of high-power transmitters to sensitive receivers.
