Introduction

Dual polarized hybrids are 5-port microwave systems that split the input power into four parts (based on polarization separation and equipolar decoupling), consequently, allow the simultaneous operation of four outdoor radio units (ODUs). Since the devices provide high inter-port isolation and low return loss, their application together with high performance antennas lead to use of four independent transmission channels on a single antenna at the same time.

DH-4ODU_def
DH–4ODU consists of one OMT (for polarization separation), and two hybrids (for equipolar decoupling)

Application

Dual Polarized Hybrids can be directly mounted on antennas that have circular waveguide connector. Alternatively, if the antenna is not ready for direct mount, and the feed system itself contains an integrated orthomode transducer, the separate mounted version of the system can be applied. The interfaces on the ODU sides are upon customer's request (coaxial cable connector, standard waveguide flange, ODU interface or any special request).
