Abstract
A dual mode radio frequency receiver or transmitter capable of operating in a terrestrial mode in which signals are routed over a terrestrial network, and a satellite mode in which signals are routed over a satellite network. The radio frequency receiver includes a terrestrial front-end RF stage which receives signals from a terrestrial network, a satellite front-end RF stage which receives signals from a satellite network, and a common RF stage which includes mixing circuitry for frequency down-converting the signals received from the front-end RF stages.
