Waveguide Tees
Waveguide tees are specialized components in microwave engineering used to split or combine signals within waveguide systems. They come in various types, including E-plane, H-plane, and Magic tees, each designed for specific signal routing applications. These devices are essential for distributing microwave energy efficiently in radar, telecommunications, and satellite communication systems, ensuring optimal signal integrity and system performance.
Double-Ridged Waveguide Magic Tees | 0.84–40.0 GHz
Dolph Microwave supplies double-ridged Magic Tees for signal addition, subtraction and division. Published models cover 0.84–40.0 GHz with WRD sizes and mating flange codes listed below. Standard data includes 100% operating bandwidth, 30 dB E/H isolation, 15 dB same-arm isolation and ±0.5 dB unbalance; DH-840DRWMT uses 1.5:1 VSWR, while the other listed models use 1.15:1.
Choose Aluminum or Copper where specified, confirm cover or grooved flange interfaces, and send any pressure-sealing or mechanical requirements with your RFQ.

Choose the Right Signal-Path Component
Need More Than a Tee Junction?
For multiway power distribution or combination, use the Double-Ridged Waveguide Divider / Combiner.
Need a Sampled RF Path?
For coupled-port measurement or monitoring, review the Double-Ridged Waveguide Couplers.
Need Standard Rectangular Waveguide?
For E-plane, H-plane or Magic Tee models in standard rectangular waveguide, review the Waveguide Tee range. For switched routing, use Waveguide Switches.
