Bi-directional communication apparatus

An apparatus, comprising:

• a first signal point;
• a second signal point;
• a third signal point;
• a first signal receiving module coupled between said first signal point and said third signal point for receiving a first RF signal from said first signal point, said first signal receiving module down-converting said first RF signal for providing a first down-converted signal at said third signal point;
• a second signal receiving module coupled between said second signal point and said third signal point for receiving a second RF signal, said second signal receiving module down-converting said second RF signal for providing a second down-converted signal at said third signal point;
• and
• a signal transmitting module coupled between said first and second signal points and said third signal point for receiving a third RF signal from said third signal point, said signal transmitting module up-converting said third RF signal for selectively providing an up-converted signal at one of said first and second signal points in response to a selection signal.

A method for processing signals, comprising the steps of:

• receiving a first RF signal provided at a first signal point;
• down-converting said first RF signal for providing a first down-converted signal at a third signal point;
• receiving a second RF signal provided at a second signal point;
• down-converting said second RF signal for providing a second down-converted signal at said third signal point;
• receiving a third RF signal provided at said third signal point;
• and
• up-converting said third RF signal for selectively providing an up-converted signal at one of said first and second signal points in response to a selection signal.
