Directional coupler
- High directivity
- Minimum coupling variation
- Low VSWR
The DC-1XE/Y and DC-2XE/Y directional couplers are used for extracting or introducing RF power flow in a transmission line without distortion of signal characteristics. The directional couplers are available in 3, 6, 10, 15, 20 dB coupling values and 30, 35 dB directivities.

| DCZ-08E/Y | 26,5 - 40 | WR-28 | 1.1 | 1.15 | 0.5 | ±0.7 |
| DCZ-06E/Y | 33 - 50 | WR-22 | 1.1 | 1.15 | 1.1 | ±0.7 |
| DCZ-04E/Y | 50 - 75 | WR-15 | 1.1 | 1.15 | 1.1 | ±0.7 |
| DCZ-03E/Y | 75 - 110 | WR-10 | 1.1 | 1.15 | 1.5 | ±0.7 |
| DCZ-02E/Y | 110 - 170 | WR-6 | 1.15 | 1.2 | 2.5 | ±0.7 |
| DCZ-015E/Y | 170 - 225 | WR-5 | 1.15 | 1.2 | 2.5 | ±0.8 |
