75-80GHz WR-12 Waveguide Circulator 3W High Isolation 18dB VN-WGCIR-7580-WR12

75-80GHz WR-12 WAVEGUIDE CIRCULATOR

• Broadband operation (multi‑octave possible)
• High transmitter‑receiver isolation
• Reduces system complexity compared to duplexers

1. Port assignment –
   A WAVEGUIDE CIRCULATOR must have its three ports clearly identified: input, output, and isolated port.

2. Signal input connection –
   Connect the transmitter or signal source to port 1 of the WAVEGUIDE CIRCULATOR.

3. Load connection –
   Connect the antenna or main transmission path to port 2 of the WAVEGUIDE CIRCULATOR.

4. Termination of isolated port –
   Always terminate the isolated port (port 3) of a WAVEGUIDE CIRCULATOR with a WAVEGUIDE LOAD to absorb reflected power.

5. Flange matching –
   A WAVEGUIDE CIRCULATOR requires the same flange type (UG, CPR, cover, or choke) as the rest of the waveguide system.

6. Magnetic bias field –
   A WAVEGUIDE CIRCULATOR typically has an internal permanent magnet; no external bias is needed for normal operation.

7. Power handling check –
   Before using a WAVEGUIDE CIRCULATOR, verify its average and peak power ratings against the system requirements.
