3.5mm Terminations
3.5mm RF Terminations are precision microwave components designed to absorb RF signal power and eliminate unwanted reflections in high-frequency transmission lines. These precision terminations maintain a stable 50 Ohm impedance, ensuring excellent signal integrity, low VSWR, and outstanding return loss across a wide frequency range. Supporting frequencies from DC to 26.5 GHz, 3.5mm RF Terminations are widely used in RF testing, microwave communication, aerospace, defense, satellite systems, radar, semiconductor testing, and calibration laboratories.
At SRFS Teleinfra, we manufacture premium-quality 3.5mm RF Terminations using precision stainless steel bodies, high-performance resistive elements, gold-plated contacts, and advanced CNC machining technology. Our RF terminations provide accurate impedance matching, excellent thermal stability, and dependable microwave performance for demanding RF applications.
Every 3.5mm RF Termination is manufactured in India under strict quality control procedures and undergoes comprehensive electrical and mechanical testing to ensure consistent performance, long service life, and reliable operation in telecom, aerospace, defense, and research applications.
What is a 3.5mm RF Termination?
A 3.5mm RF Termination is a passive RF load that absorbs incident RF energy and terminates unused RF ports without reflecting signals back into the system. It provides an accurate 50 Ohm impedance match, protecting sensitive RF equipment and ensuring accurate microwave measurements.
The 3.5mm precision connector interface supports operation up to 26.5 GHz, making it ideal for laboratory-grade measurements, Vector Network Analyzer (VNA) calibration, production testing, and high-frequency communication systems.
