4.5cm broad band C/X secondary focus receiver (4000-9300 MHz)
This is a broad-band receiver with two orthogonal linear polarizations (at a 45°-angle with the horizon). The receiver delivers 4 basebands (each with two polarizations):
| Baseband | Center Frequency | Bandwidth |
|---|---|---|
| 1 | 5.250 GHz | 2500 MHz |
| 2 | 6.750 GHz | 2500 MHz |
| 3 | 6.668 GHz | 200 MHz |
| 4 | 4.829 GHz | 200 MHz |

Comments:
- The gain curve was corrected for opacity (though it is small, < 0.02 throughout the band).
