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.

[What we claim is:] [1.]a first front-end RF stage for receiving a terrestrial signal of the terrestrial network and providing a first output signal with a characteristic of the terrestrial signal;a second front-end RF stage for receiving a satellite signal of the satellite network and providing a second output signal with a characteristic of the satellite signal;a common RF stage including an input for receiving either the first output signal or the second output signal and including mixing circuitry for frequency down-converting the first and second output signal to enable subsequent decoding;a switch for selectively coupling either said first output signal or said second output signal to said common RF stage; andmeans for substantially equalizing a frequency of said first output signal with a frequency of said second output signal, wherein said switch is located between said equalizing means and said common RF stage, said equalizing means providing substantial equalization between the frequencies of said first and said second output signals before application of said first and said second output signals to said switch.
