Abstract
A circuit with co-matching topology for transmitting and receiving RF signals, said circuit comprising: a first sub-circuit comprising a first inductive component and a first capacitive component to form a low-pass filter for transmitting a first RF signal from a first amplifier to an antenna, wherein the first inductive component is coupled to a ground via a first switch; and a second sub-circuit comprising a second inductive component and a second capacitive component for receiving a second RF signal from the antenna to an input terminal of a second amplifier, wherein said input terminal of the second amplifier is coupled to the ground via a second switch; wherein when the first amplifier is transmitting the first RF signal, the first switch is turned off and the second switch is turned on, and wherein when the second amplifier is receiving the second RF signal, the first switch is turned on and the second switch is turned off.
