Dual Polarization Antennas

This series of scalable and dual polarization antennas is designed for WiMAX. The new antennas are scalable, ranging from 2 to 12 beams and offer single and dual polarization — vertical and horizontal operating capability. As an example, from one antenna/single cell site, 72 beams can be deployed in six sectors. The antennas operate at high frequencies of up to 11 GHz and at the most common frequencies of WiMAX profiles. The antenna system’s scalability allows the operators and service providers to meet the continued and/or sudden capacity growth demands without installing new antennas and associated processes.

Passive Components

This series of passive components is aimed at the satellite, commercial, radio and air traffic communications industries as well as test and measurement. The range includes power divider/combiners, directional couplers and hybrid couplers. Operating at frequencies between 200 and 10,000 MHz, the resistor-less, two-, three- or four-way divider/combiners have the same power handling performance whether used as a divider or combiner up to a maximum of 500 W. When used as a divider, the power is split equally between all outputs so long as all ports are correctly matched with 50 Ω impedance. In power combining applications, the insertion loss is extremely low when the input signals are coherent and in-phase.
