Abstract :
An outphasing system at 2.14 GHz using LDMOS power amplifiers with an attempt to use composite right/left handed material transmission (CRLH) lines in the combiner part is presented. Linear amplification using nonlinear components (LINC) is a method that improves linearity without cost in power efficiency. By summing two constant-envelope phase modulated signals this system exhibits high efficiency performance since the amplifiers used can be operated close to saturation levels and still get reasonably linear output
