Claim Text:
1. A radio frequency communication system, comprising; an antenna; an amplifier electrically connected to the antenna to amplify a common-mode signal transmitted by the antenna and outputting an amplified common-mode signal; and a noise isolating unit electrically connected to the amplifier to isolate the amplified common-mode signal, wherein the noise isolating unit includes; a first transformer including a first primary winding and a first secondary-winding, wherein the first primary winding is electrically connected to the amplifier; a second transformer including a second primary winding and a second secondary winding, wherein the second primary winding is electrically connected to the first secondary winding to isolate the transmission of the amplified common-mode signal; and a plurality of capacitors; wherein, the first transformer cooperates with at least one of the capacitors to isolate the transmission of a part of the amplified common-mode signal, and the second transformer cooperates with at least one of the capacitors to Isolate the -transmission of a remaining part of the amplified common-mode signal.
