A waveguide tee is a three-port device used in microwave systems to split or combine signals. It comes in various forms, including E-plane, H-plane, and Magic tees, each designed for specific applications. This component is essential for directing RF energy in multiple directions, enhancing system design flexibility.
Dolph Microwave supplies 3-port E-plane and H-plane tees plus 4-port magic hybrid tees from WR2300 to WR10, covering 0.32–112 GHz. Standard catalog models include multiple flange configurations, with custom mechanical and electrical specifications available. Send your operating frequency, waveguide size, tee type, flange and performance targets for model selection.
A 4-port coupler for matching, balance and isolation. With the E-plane port used as input, the two collinear outputs are 180° out of phase; with the H-plane port as input, the outputs are in phase. Equal-amplitude, in-phase signals applied to the two collinear ports combine at the H-plane port and cancel at the E-plane port.
Catalog values: 20% operating bandwidth, E-port VSWR 1.15:1, H-port VSWR 1.2:1, ±0.25 dB unbalance, 35 dB E/H isolation and 20 dB same-arm isolation.
A 3-port tee with the auxiliary-arm junction on the broad wall of the main waveguide. It is available throughout the catalog range from WR2300 to WR10.
Catalog values: 100% operating bandwidth, E-port VSWR 1.15:1 and ±0.25 dB E/H unbalance.
A 3-port tee with the auxiliary-arm junction on the narrow wall of the main waveguide. It is available throughout the catalog range from WR2300 to WR10.
Catalog values: 100% operating bandwidth, H-port VSWR 1.15:1 and ±0.25 dB E/H unbalance.
Standard models span WR2300 to WR10; detailed electrical and flange values are listed below.
