摘要：
An apparatus comprising:
power amplifier circuitry;
proximal filter circuitry proximal to the power amplifier circuitry;
means for routing output of the power amplifier circuitry to the proximal filter circuitry to be filtered for transmission;
means for routing output of the power amplifier circuitry to remote filter circuitry remote from the power amplifier circuitry to be filtered for transmission;
wherein the proximal filter circuitry is configured to provide for transmission in a transmission bandwidth of a first band, reception in a reception bandwidth of the first band and reception in a reception bandwidth of the second band and comprises
a proximal duplexer configured for the transmission bandwidth of the first band and the reception bandwidth of the first band, a proximal bandpass filter for the reception bandwidth of the second band and a proximal diplexer for isolating the transmission bandwidth of the first band and the reception bandwidth of the second band.
