High-Power DC-Blocks up to 18 GHz for RF and Microwave Systems
DC-blocks are essential passive components in RF and microwave systems, serving to isolate DC voltage while maintaining unimpeded AC signal transmission. These high-power DC-blocks operate up to 18 GHz, designed to meet the demanding requirements of modern communications and industrial RF applications. The components deliver robust performance across ultra-wideband frequency ranges while handling substantial power levels.
Technical Specifications
- Frequency Range: 0.01 to 18 GHz continuous bandwidth
- Power Handling: 100 Watts continuous
- DC Isolation: 200 V DC blocking performance
- Connectors: N-type (male and female configurations)
- Customization: Custom design variants available for specialized applications
- Extended Range: DC-blocks available up to 110 GHz for higher frequency bands
The broad frequency coverage from 10 MHz to 18 GHz positions these components as viable solutions for systems requiring seamless transition across L-band, S-band, C-band, X-band, and Ku-band operations. The 100-watt power handling capacity ensures compatibility with high-power amplifier output stages, while the 200 V isolation specification provides adequate protection for downstream low-noise amplifiers and sensitive receiver front-ends against parasitic DC voltages.
Application Areas
- 5G/6G & Telecommunications: Infrastructure deployment and testing systems for next-generation wireless networks
- SATCOM: Ground stations and satellite communication terminals requiring DC isolation
- Defense & Aerospace: Military RF systems and broadband amplifier chains
- Test & Measurement: RF laboratories, microwave instrumentation, and characterization setups
The availability of N-type connectors ensures straightforward integration into existing coaxial RF systems, while custom designs accommodate non-standard connector requirements such as SMA, TNC, or specialized implementations.
