RF directional coupler – 0.15 to 40 GHz, up to 300 W | JQL Electronics / Dorado
JQL RF directional couplers from 0.15 to 40 GHz with coupling values up to 40 dB, Low-PIM versions and power ratings up to 300 W.
The JQL Technologies Directional Couplers are passive RF components designed to couple a defined portion of the transmitted RF power from a main signal path. The product family includes models from 0.15 to 40 GHz with different coupling, insertion loss, directivity, return loss and power characteristics.
The range provides coupling factors from a few decibels up to 40 dB. Several models also include specified PIM performance for applications with demanding passive-intermodulation requirements.
Advantages
- Wide frequency coverage: listed models from 0.15 to 40 GHz.
- Multiple coupling values: configurations from 4.8 dB to 40 dB.
