Standard Waveguide_High-Power Waveguide Coaxial Adapter
Dolph Microwave High-Power Waveguide Coaxial Adapter precision adapters operate from 0.32 GHz to 112 GHz across WR-2300 to WR-10 sizes. Featuring ultra-low 1.2:1 VSWR, 0.25 dB insertion loss, and 1,500W power handling, these all-metal adapters deliver unmatched signal integrity for radar, SATCOM, and 5G infrastructure. Connectors include N-type, 2.92mm (K), and 7-16 DIN.
Product Overview
Dolph Microwave’s premium waveguide-to-coaxial adapters bridge waveguide transmission lines and coaxial interfaces with uncompromising precision. Engineered for high-power applications from 1.72 GHz to 67 GHz, these adapters support WR sizes spanning WR-2300 to WR-10 and feature industry-standard coaxial connectors (7-16 DIN, N-type, 2.92mm/K, 1.85mm/V). With exceptional voltage standing wave ratio (VSWR) performance as low as 1.2:1 and insertion loss capped at 0.25 dB, they ensure signal integrity in critical communications infrastructure. All-metal construction eliminates dielectric beads, maximizing power handling to 1,500W average in lower bands.
Key Features & Engineering Superiority
- High-Power Design: Robust all-metal (Al/Cu) construction withstands up to 1,500W average power (lower frequencies), ideal for radar and satcom.
- Ultra-Low VSWR: Maintains ≤1.2:1 VSWR across bands, minimizing signal reflections.
- Precision Air Line Connectors: Grounded center conductor and air dielectric interface reduce passive intermodulation (PIM).
- Space-Quality Option: Low-outgassing variants (TML/RML <1%, CVCM <0.1%) available for vacuum environments.
- Corrosion Resistance: SurTec-treated aluminum flanges with chromate conversion and flat black paint (custom finishes optional).
Critical Applications
- Radar systems (airborne/ground-based)
- Satellite communication (SATCOM) payloads
- 5G/6G wireless base station backhaul
- RF testing & measurement (lab/field)
- Military and aerospace communications
