Microwave Couplers/Hybrids

Microwave couplers/hybrids are 3-port microwave waveguide systems that split the input power into two parts, hence enabling the simultaneous operation of two outdoor radio units (ODUs) and realizing the two independent transmission channels on a single antenna at the same time.

Microwave Antennas

Key Features:

Low Profile Antennas

Ultra-High Performance Antennas

Size: 0.3m-2.4m

Frequency: 6GHz-38GHz

High product quality

Single and dual polarized

Easy upgrade in field

Shorter lead time

Simple installation

Customized Antenna: LPC series can be provided with a customer designed adaption for the ODU. This allows the ODU to be directly mounted to the antenna.
