TEMcoupler - RF/Microwave Design Software for Directional Couplers.
​Where Synthesis enables Analysis™

Software Product: TEMcoupler - Multi-section TEM Directional Couplers

Atlanta RF Software offers RF/microwave CAE software product: ​TEMcoupler, which performs electrical and dimensional Synthesis of N-section Symmetrical and Asymmetrical Directional Couplers and/or Frequency Analysis of TEM-mode (stripline) or quasi-TEM-mode (microstrip) Symmetrical or Asymmetrical Directional Couplers. Some product features:

1. Synthesis of N-section Symmetrical TEM-mode (stripline) and quasi-TEM-mode (microstrip) Directional Couplers, up to N = 9 sections across multiple frequency octaves: Zoe & Zoo.
2. Synthesis of N-section Asymmetrical TEM-mode (stripline) and quasi-TEM-mode (microstrip) Directional Couplers, up to N = 6-sections across multiple frequency octaves: Zoe & Zoo.
3. Synthesis of physical dimensions of N-section Symmetrical & Asymmetrical TEM-mode couplers using broadside parallel-coupled stripline construction, with or without strip offset.
4. Frequency Analysis of multi-section Directional Couplers:
   1. Analysis of N-section Symmetrical (N = 3, 5, 7 & 9-sections) Directional Couplers.
   2. Analysis of N-section Asymmetrical (up to N = 6-sections) Directional Couplers.
   3. Can read User's Coupler Data File or User can enter key design data for Analysis:
      1. Even and Odd-Mode Impedances: Zoe & Zoo for each section.
      2. Center Frequency for each section.
5. Frequency Analysis features:
   1. User can select even & odd-mode phase velocity to simulate Microstrip construction.
   2. User can select loss levels (dB/inch) to simulate Insertion Loss effects.
6. Frequency Analysis response profile of key 4-port directional coupler parameters.
   1. 4-port Coupler Response: Scattering Parameters - Magnitude (dB) & Phase (deg).
   2. VSWR, Coupling, Isolation & Quadrature Phase Error.
7. Default values for each User-entered Input Data.​

Software product: TEMcoupler is a User-friendly and versatile design tool to characterize practical multi-section directional couplers having a symmetrical or asymmetrical design, whether constructed in stripline or dispersive microstrip.
