4.3-10 mm Attenuator
4.3-10 Attenuators are precision RF components designed to reduce signal power while maintaining excellent impedance matching, low VSWR, and superior RF performance. They are primarily used in 4G LTE, 5G mobile communication networks, Distributed Antenna Systems (DAS), base stations, remote radio units (RRUs), antennas, and wireless infrastructure where precise signal level control is required. Supporting frequencies from DC to 6 GHz, with some precision variants available up to 12 GHz, 4.3-10 Attenuators deliver reliable performance for modern cellular communication systems.
At SRFS Teleinfra, we manufacture premium-quality 4.3-10 Attenuators using precision thin-film resistor technology, high-quality 4.3-10 connectors, and advanced CNC machining. Our attenuators provide low insertion loss, excellent return loss, high power handling capability, and exceptional Passive Intermodulation (PIM) performance for demanding RF applications.
Every 4.3-10 Attenuator is manufactured in India under stringent quality control procedures using premium raw materials. Each unit undergoes comprehensive electrical and mechanical testing to ensure stable attenuation, reliable RF performance, and long operational life.
What is a 4.3-10 Attenuator?
A 4.3-10 Attenuator is a passive RF device that reduces the power level of an RF signal by a fixed attenuation value while maintaining a constant 50 Ohm impedance. It protects sensitive RF equipment, minimizes signal reflections, and improves system performance.
The 4.3-10 connector was specifically developed as a compact, low-PIM replacement for the traditional 7/16 DIN connector used in mobile communication infrastructure. It offers reduced installation torque, improved mechanical reliability, excellent weather resistance, and outstanding RF performance.
