YUSNTECH has expanded its portfolio of high-performance Coaxial RF Isolators, offering frequency coverage from 40 MHz to 40 GHz and power handling up to 300 W. Designed for reflected power protection, signal stability, and RF system reliability, these microwave isolators support a wide range of applications including satellite communications, radar systems, electronic warfare (EW), RF power amplifiers, telecommunications infrastructure, aerospace electronics, and test & measurement equipment.
As RF and microwave systems continue to operate at higher power levels and wider bandwidths, reflected signals caused by antenna mismatches or load variations can significantly impact system performance. YUSNTECH coaxial isolators are engineered to absorb reverse power while maintaining low insertion loss, high isolation, and excellent impedance matching, helping protect valuable RF components and improve overall system efficiency.
Wide Frequency Coverage from VHF to Millimeter Wave
The YUSNTECH coaxial isolator family covers frequencies from 40 MHz to 40 GHz, supporting applications ranging from VHF/UHF communications to microwave and millimeter-wave systems.
Available product configurations include:
- 40 MHz to 1 GHz high-power coaxial isolators for telecom infrastructure, public safety radio, and broadcast systems.
- 1 GHz to 8 GHz RF isolators for wireless communications, radar transmitters, and RF power amplifier protection.
- 6 GHz to 18 GHz broadband microwave isolators for electronic warfare systems, spectrum monitoring, and wideband test equipment.
- 17 GHz to 40 GHz K-band isolators for satellite communications, aerospace electronics, microwave instrumentation, and high-frequency laboratory applications.
Depending on the model, isolation levels reach up to 25 dB while insertion loss can be as low as 0.2 dB, ensuring efficient signal transmission and superior reverse signal suppression.
