GRANTE Antenna Development and Production Corporation

Introduction

Single polarized hybrids are 3-port microwave waveguide systems that split the input power into two parts, consequently, allow the simultaneous operation of two 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 two independent transmission channels on a single antenna at the same time.

Hybrids divide the input power into two (not necessarily equal) parts with identical polarization

Upgrading Wireless Links

The transmission capacity of the microwave link can be doubled by using the two outdoor radio units (ODUs) in simultaneous operation mode (on different frequency channels). The link availablilty may be increased by several orders of magnitude in hot standby mode (the second radio is for the immediate replacement of the main ODU in case of failure).

GRANTE hybrids can be attached to the back of the antennas in direct and separate mounted ways. The interfaces on the ODU side are upon customer's request (N connector, standard waveguide flanges, ODU interface or any special request).
