Product Description

The UHF Wideband Coaxial Isolator is a high-reliability RF component designed for the 300-400MHz frequency range. Featuring a clockwise signal direction and low insertion loss, it is an ideal choice for protecting active microwave components in Commercial and Space applications.

Application Scenarios

  • Military Communications: Robust signal protection for UHF radio systems in demanding field operations.
  • Aerospace Systems: High-isolation performance tailored for satellite and space-grade hardware.
  • Broadcasting: Ensures signal integrity by preventing reflected waves from damaging high-power transmitters.

Frequently Asked Questions

Q1: What is the significance of the "Clockwise" direction?
A: The Clockwise direction defines the path the signal takes from the input to the output. Our engineering team can also provide counter-clockwise configurations upon request.
Q2: Can this isolator handle more than 50W of power?
A: The standard power rating is 50W CW. For higher power needs, we can provide custom technical specifications to match your system's power level.
Q3: Is the N-Female connector the only option?
A: While N-Female is common for these UHF Wideband applications, we offer OEM services for various connector types like SMA or DIN.
Q4: Do you offer 24-hour engineer support?

A: Yes, you can contact our salesmen and engineers 24 hours a day for professional skills support and assistance with any project requirements.
