Frequently Asked Questions (FAQ)
Q: What is the maximum frequency of the 1.85-KFD1-SMT Solderless RF Connector?
A: The 1.85-KFD1-SMT supports a frequency range from DC to 67GHz with a maximum VSWR of 1.35. This makes it suitable for millimeter-wave test fixtures, 5G base station prototypes, and high-frequency measurement systems.
Q: Why choose a solderless RF connector over a soldered type?
A: A solderless RF connector avoids thermal damage to sensitive PCB laminates and dielectric materials during installation. The compression-mount design also allows rapid prototyping, repeated assembly, and easy reconfiguration without degrading board or connector performance.
Q: What materials are used in the 1.85-KFD1-SMT?
A: The 1.85-KFD1-SMT uses a stainless steel body for mechanical durability, beryllium copper contacts for low contact resistance, and PEI dielectric to maintain stable 50 Ohm impedance across the full DC to 67GHz frequency range.
