A radio frequency integrated circuit includes a power amplifier, a low
noise amplifier, a first transformer balun, and a second transformer
balun. The power amplifier includes a first power amplifier section and a
second power amplifier section. 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. The power amplifier provides the first
amplified outbound RF signal to the first transformer balun and the
second outbound RF signal to the second transformer balun, where the
first transformer balun is coupled to a first antenna and the second
transformer balun is coupled to a second antenna. The low noise amplifier
includes a first low noise amplifier section and a second low noise
amplifier section. When enabled, the first low noise amplifier section
amplifies a first inbound RF signal to produce a first amplified inbound
RF signal, and, when enabled, the second low noise amplifier section
amplifies a second inbound RF signal to produce a second amplified
inbound RF signal. The low noise amplifier receives the first inbound RF
signal from the first transformer balun and receives the second inbound
RF signal from the second transformer balun.
