Description
Introduction
Hualink provides a full range of in-series and between - series high performance, high quality, precision adaptors, it performs very low VSWR and insertion loss. These 50 ohms SMA to SMA adaptors are designed in very stringent tolerances, manufactured following strict procedures, and checked completely. Heat treated gold plated beryllium coppers center pin and SUS body ensure that adaptors have better "anti-corrosion", "wear-resisting" to reach more mating/unmating cycles.

FAQ
1. Cut-off frequency of RF connector?
2. Hualink's SMA Connectors
SMA is an acronym for SubMiniature version A and was developed in the 1960's. The working frequency of SMA series can reach up to 27GHz. It adopts reliable screw connection method, which is widely used in communication, testing, automobile, satellite, radar, radio astronomy and other fields. The dielectric adopts material of PTFE/Teflon. Due to simple structure and small volume, this series can work at higher frequencies. The interface is compatible with 3.5 mm, 2.92 mm, SMK, and K series connectors.
3. How much torque is recommended for a RF connector?
Connector Type | Recommended Coupling Torque |
SMA | 7 - 10 lb-in |
3.5 mm | 7 - 8 lb-in |
2.92 mm | 7 - 8 lb-in |
2.4 mm | 7 - 8 lb-in |
1.85 mm | 7 - 8 lb-in |
1.0 mm | 3.6 - 4.4 lb-in |
Type N | 12- 15 lb-in |
