Isolators up to 40 GHz

Coaxial Isolators up to 40 GHz – Unidirectional Signal Isolation for RF and Microwave Systems

Coaxial isolators up to 40 GHz are essential passive components for decoupling and protecting sensitive RF circuits from reflections and reverse power. They ensure unidirectional signal flow and minimize VSWR issues in high-frequency system architectures.

Key Features

• Frequency Range: DC to 40 GHz – coverage from L-band to Ka-band and beyond
• High Isolation: Typically 20 dB and higher for reliable signal unidirectionality
• Low Insertion Loss: < 0.5 dB in most bands for maximum signal integrity
• Multiple Form Factors: Drop-in, SMT and dual junction isolators for flexible integration
• High Power Handling: Available up to medium-high power class for HPA and transmitter applications
• Coaxial Interfaces: SMA, N-type and other standard connectors

Applications

• SATCOM and telecommunications systems with critical reflection requirements
• 5G/6G RF frontend and mmWave component protection
• Defense, radar and ADAS systems with high reliability requirements
• Test and Measurement equipment for signal path independence
• LNA and HPA chains with impedance matching and isolation requirements

Isolators prevent instability and gain compression caused by reverse power. They are critical particularly in transmit chains and upstream of sensitive low-noise stages. Our isolators meet Mil-Spec standards and deliver reproducible performance across wide temperature and frequency ranges.
