YUSNTECH provides a comprehensive and established portfolio of coaxial RF isolators, including both single junction and dual junction isolator series, designed for reliable RF power amplifier protection, reflected power absorption, and high isolation performance in microwave and RF systems.
Covering a wide frequency range from VHF/UHF bands to microwave and millimeter-wave frequencies, YUSNTECH coaxial isolators are widely used in radar systems, satellite communications, electronic warfare (EW), RF power amplification chains, telecommunications infrastructure, and RF test and measurement systems.
Coaxial RF Isolators for Reflected Power Protection
A coaxial RF isolator is a passive microwave component that allows RF signals to pass in one direction while absorbing reflected power in the reverse direction. This function is essential for protecting sensitive RF components such as power amplifiers, transmitters, and receiver front ends from damage caused by impedance mismatch or antenna reflection.
YUSNTECH coaxial isolators are engineered to ensure stable system performance, low signal distortion, and reliable reflected power handling under continuous and high-power operating conditions.
Complete Product Line: Single Junction and Dual Junction Isolators
YUSNTECH offers a complete and mature product portfolio of coaxial isolators, designed to meet different RF system requirements.
Single Junction Coaxial Isolators
Single junction isolators are widely used in standard RF and microwave applications where compact size, cost efficiency, and stable performance are required. They provide:
- Low insertion loss
- Standard isolation performance
- Compact coaxial structure
- Reliable RF protection for general applications
Typical applications include wireless communication systems, RF modules, laboratory test equipment, and general RF amplifier protection circuits.
Dual Junction Coaxial Isolators
Dual junction isolators use two magnetic junction stages to achieve enhanced performance for demanding RF environments. Compared with single junction designs, they provide:
- Higher isolation performance
- Improved reflected power handling capability
- Enhanced stability in high-power operation
- Stronger protection for RF power amplifiers
They are widely used in radar systems, electronic warfare platforms, satellite communication systems, and high-power RF transmission systems, where system reliability and signal integrity are critical.
