We are suggesting the directional coupler on multi connected lines with 3 dB transient attenuation (Lange bridge) in hybrid-integrated implementation (DIC).
Various modifications of these devices are released:
| Modifications | Frequency range,GHz |
| DC 1-2 | 1…2 |
| DC 2-4 | 2…4 |
| DC 4-8 | 4…8 |
All products modification can be delivered as printed-circuit board and as case with SMA-F connectors by customer request.
Are used in:
- power dividers and power combiners;
- balanced circuits of power amplifiers;
- balanced mixers;
- mixers with image channel suppression;
- phase shifters;
- duplexers;
- beam formes.
