Description
The SMA Female Solder Connector for SM 250 is a professional-grade RF interface designed for the most demanding high-frequency environments. Unlike standard flexible cables, the .250″ Semi-Rigid (SM 250) cable features a solid copper outer conductor. This connector is precision-machined to slide directly onto the cable’s outer jacket, allowing for a 360-degree solder joint that ensures absolute shielding and mechanical permanence.
Engineered for Microwave Excellence By soldering the connector body directly to the cable’s solid copper shield, this interface eliminates the leakage and PIM (Passive Intermodulation) issues associated with crimped or clamped connectors. It is the gold standard for RF power amplifiers, base stations, and laboratory test fixtures where the signal path must remain undisturbed up to 18 GHz.
Key Technical Advantages:
-
Optimized for SM 250: Custom-bored internal diameter ensures a perfect friction-fit over .250-inch semi-rigid or conformable (hand-formable) cable types.
-
Direct-Solder Body: Provides the lowest possible contact resistance and the highest mechanical strength, ensuring the connector remains stable even under thermal expansion.
-
Superior EMI Shielding: The seamless solder connection provides essentially 100% RF shielding, protecting sensitive signals from external interference.
-
Low VSWR & Insertion Loss: Maintains a strict 50 Ohm impedance throughout the transition from cable to connector, crucial for high-performance microwave transmission.
-
Premium Plating: Constructed from high-purity gold-plated brass or stainless steel with a gold-plated beryllium copper center contact for lifelong corrosion resistance and excellent solderability.
