Diseño RF de un transmisor MIMO UWB

Abstract

An ultra wide band MIMO transmitter using a six way splitter is presented in this document. It has been designed as an hybrid circuit in an Arlon substrate to be confined in the smallest space at the desired frequency range. The aim of the proposed system is the integration of MIMO and UWB to obtain most advantages of both technologies and to balance their disadvantages. Although UWB is a suitable option if inexpensive costs are taking into account, it is limited to short range applications due to its very low transmitted power. But MIMO technique in UWB systems improve the link robustness of UWB or its data rate, exploiting multipath and diversity gain to improve the SNR without consuming extra radio frequency. This is only valid if the antennas are placed appropriately distance among them.
