Directional Coupler (LNDC)

LNDC block


The LNDC is a standard coupler which is integrated with a low noise amplifier on the coupled port for added output power and port-to-port isolation. A wide selection of amplifiers and customized input/output attenuators provide flexibility in setting gain and power levels. The integrated design makes the LNDC module an excellent space saving option, eliminating the need for an external amplifier and splitter. Please consult our technical staff for assistance in configuring an LNDC module to meet your needs.
