Transmitter for point-to-point radio system

Abstract

Embodiments of the present invention are directed to methods, apparatuses, and systems for implementing a point-to-point radio architecture in which the isolation needed between the transmitter and receiver may be achieved through the use of separate antennas. One embodiment is directed at a radio head comprising a transmitter configured to operate at a first frequency, a receiver configured to operate at a second frequency, and a processor coupled to both the transmitter and the receiver. The transmitter is further coupled to a first antenna interface coupled to a first antenna configured to transmit signals at the first frequency. The receiver is further coupled to a second antenna interface coupled to a second antenna configured to receive signals at the second frequency.

AI Technical Summary

Benefits of technology

[0008]Embodiments disclosed herein implement a radio architecture in which the isolation needed between the transmitter and receiver may be achieved through the use of separate antennas. The separate antennas may have sufficient isolation to (1) block the high power levels of the transmitter from desensitizing or damaging the receiver circuits within the transmitted spectrum, and (2) block the noise transmitted by the transmitter within the receive spectrum.

Problems solved by technology

However, existing systems implementing these techniques incorporate filters, diplexers, couplers, Ortho-Mode Transducer (OMT), and / or other elements that lead to signal loss and degradation of signals, higher costs, more weight, increased complexity, constraints on transmission range of components, and additional design problems.
