FAQ
A broadband coaxial isolator is a non-reciprocal RF and microwave component designed to provide signal transmission in one direction while absorbing reflected power over a wide frequency range. It protects sensitive RF components and maintains stable system performance across broad operating bandwidths.
Broadband coaxial isolators offer wide frequency coverage, low insertion loss, excellent VSWR, and reliable reflected power protection. They simplify system design by supporting multiple frequency bands with a single device and are ideal for wideband RF and microwave applications.
Standard isolators are typically optimized for relatively narrow frequency bands, while broadband coaxial isolators maintain stable electrical performance over much wider frequency ranges. They are particularly suitable for applications requiring wide instantaneous bandwidth or multi-band operation.
YUSNTECH broadband coaxial isolators are available across multiple frequency bands from VHF and UHF frequencies to microwave bands up to 18 GHz. Standard and custom frequency ranges are available to meet specific system requirements.
Broadband coaxial isolators are widely used in electronic warfare systems, radar systems, satellite communications, RF test and measurement equipment, spectrum monitoring systems, broadband receivers, and wireless communication infrastructure.
Electronic warfare and spectrum monitoring systems often operate across wide instantaneous bandwidths. Broadband coaxial isolators provide stable isolation and reflected power protection across the operating spectrum, improving signal integrity and system reliability.
Key selection parameters include operating frequency range, insertion loss, isolation, VSWR, forward CW power, reverse power handling, connector type, and mechanical dimensions. The required operating environment and system bandwidth should also be considered.
Yes. Depending on frequency and model configuration, YUSNTECH broadband coaxial isolators support a wide range of forward and reverse power ratings, providing reliable protection for high-power RF amplifiers and microwave transmitters.
Common connector options include SMA and N-Type connectors. Additional connector configurations and custom interfaces can be provided for specialized applications and system integration requirements.
Yes. YUSNTECH offers customized broadband coaxial isolator solutions, including custom frequency ranges, power ratings, connector types, isolation requirements, mechanical configurations, and environmental specifications to meet OEM and system integration needs.
By absorbing reflected power and maintaining stable impedance characteristics across a wide frequency range, broadband coaxial isolators protect RF power amplifiers and other sensitive components, reduce system downtime, and improve long-term operational reliability.
YUSNTECH provides a comprehensive portfolio of broadband coaxial isolators featuring wide frequency coverage, low insertion loss, high isolation, flexible customization, and competitive lead times for radar, electronic warfare, satellite communication, telecom, and RF test applications.
