Component Specifications

Definition
A specialized coaxial connector designed to interface RF signals from external sources into a spectrum analyzer, ensuring minimal signal loss, impedance matching (typically 50 ohms), and shielding against electromagnetic interference for accurate frequency and amplitude analysis.
Working Principle
Operates by providing a secure, low-loss electrical pathway for RF signals through a coaxial structure, maintaining characteristic impedance to prevent reflections, with shielding to minimize noise and preserve signal integrity during transmission to the analyzer's input stage.
Materials
Body: Brass or stainless steel with gold or silver plating; Dielectric: PTFE (Teflon) or polyethylene; Contacts: Beryllium copper or phosphor bronze with gold plating; Insulation: High-temperature resistant polymers.
Technical Parameters
  • VSWR <1.5:1
  • Impedance 50 ohms
  • Durability 500 mating cycles
  • Connector Type SMA, N-type, or BNC
  • Insertion Loss <0.5 dB
  • Frequency Range DC to 18 GHz
  • Operating Temperature -55°C to +125°C
Standards
IEC 61169, MIL-PRF-39012
