High-Power Waveguide Coaxial Adapter
Engineered for precision RF systems, Dolph Microwave’s High-Power Waveguide Coaxial Adapter bridges double-ridged waveguides (WRD840 to WRD750) and coaxial interfaces (DIN 7-16, N-type) with unmatched performance. Featuring ultra-low VSWR (1.25:1), minimal insertion loss (≤0.4 dB), and high-power handling (up to 1000W), it ensures reliability in radar, satellite communications, and 5G base stations.
Product Overview
Dolph Microwave’s Double Ridged High-Power Waveguide Coaxial Adapters are engineered to seamlessly integrate waveguide and coaxial systems across a broad frequency spectrum (0.84 GHz to 40 GHz). Designed for demanding applications, these adapters feature ultra-low VSWR (1.25:1 typical), minimal insertion loss (0.3 dB max), and robust power handling (up to 1000W average). Compatible with WRD840 to WRD750 waveguide standards and high-power connectors like DIN 7-16 and N-type, they ensure reliable performance in mission-critical environments such as radar, satellite communications, and 5G base stations.
Key Features
- High Power Handling: Supports up to 1000W average power (model-dependent).
- Broadband Performance: Operates from 0.84 GHz to 40 GHz with optimized impedance matching.
- Low VSWR: ≤1.4:1 across the entire frequency range.
- Low Insertion Loss: ≤0.4 dB ensures minimal signal degradation.
- Rugged Construction: Precision-machined aluminum or aluminum-copper composite, finished with corrosion-resistant Surtec 650 or chromate coating.
- Versatile Connectivity: Compatible with DIN 7-16, N-type (female/male), and SMA connectors.
Applications
- Radar Systems: High-power pulse transmission for military and aviation radar.
- Satellite Communications: Low-loss signal routing in C/X/Ku-band SATCOM.
- 5G Infrastructure: Backhaul and mmWave base station testing.
- Test & Measurement: Calibration and signal integrity validation up to 40 GHz.
- Wireless Networks: DAS (Distributed Antenna Systems) and RF front-end integration.
