1. An apparatus comprising:
a first circuit comprising a first plurality of low noise amplifiers (LNAs) each having an input and having outputs that are combined to form a first combined output, the first plurality of LNAs being for a first radio technology;
a second circuit comprising a second plurality of LNAs each having an input and having outputs that are combined to form a second combined output, the first plurality of LNAs being distinct from the second plurality of LNAs, the second plurality of LNAs being for the first radio technology;
a selecting device configured to select at least one LNA of the first or second plurality of LNAs to amplify an input radio frequency (RF) signal and provide an amplified RF signal;
a first duplexer coupled to a first switch of the selecting device and a second duplexer coupled to a second switch of the selecting device, the first duplexer and the second duplexer coupled to the input of respective LNAs of the first plurality of LNAs;
a third duplexer coupled to a third switch of the selecting device and a fourth duplexer coupled to a fourth switch of the selecting device, the third duplexer and the fourth duplexer coupled to the input of respective LNAs of the second plurality of LNAs;
a first power amplifier coupled to the first duplexer via a fifth switch and to the second duplexer via a sixth switch;
a second power amplifier coupled to the third duplexer via a seventh switch and to the fourth duplexer via an eighth switch, wherein the selecting device is distinct from one or more of the fifth switch, the sixth switch, the seventh switch, and the eighth switch; and
an integrated circuit (IC), distinct from the first circuit and the second circuit, comprising:
first receive circuits to process the amplified RF signal via a first interconnection coupled to the first combined output of the first plurality of LNAs and comprising a first amplifier having an input coupled to the first interconnection and an output coupled to a first mixer, wherein the first amplifier is bypassable,
second receive circuits to process the amplified RF signal via a second interconnection coupled to the second combined output of the second plurality of LNAs and comprising a second amplifier having an input coupled to the second interconnection and an output coupled to a second mixer, and
a first transmit circuit coupled to the first power amplifier and a second transmit circuit coupled to the second power amplifier.
