Abstract:
1. A radio frequency integrated circuit (RFIC) having an antenna diversity structure, the RFIC comprises: power amplifier halving a first power amplifier section and a second power amplifier section, wherein, when enabled, the first and second power amplifier sections amplify an outbound radio frequency (RF) signal to produce a first amplified outbound RF signal and a second amplified outbound RF signal, respectively, wherein the first amplified outbound RF signal is provided to a first transformer balun and the second outbound RF signal is provided to a second transformer balun, and wherein the first transformer balun is coupled to a first antenna and the second transformer balun is coupled to a second antenna; and low noise amplifier having a first low noise amplifier section and a second low noise amplifier section, wherein, when enabled, the first low noise amplifier section amplifies a first inbound RF signal to produce a first amplified inbound RF signal, wherein, when enabled, the second low noise amplifier section amplifies a second inbound RF signal to produce a second amplified inbound RF signal wherein the first inbound RF signal is received via the first transformer balun and the second inbound RF signal is received via the second transformer balun.
