Patent abstract
The present invention relates to balanced power amplifier network in combination with outphasing techniques such as Chireix. The object of the present invention is to provide a solution to the problem to combine balanced amplifiers like the current mode class D (CMCD) or class E/F with a LINC network. The main problem is that some power amplifiers have balanced output and the LINC network is single-ended so that a high power low loss transformer that works at several impedance levels is needed, which is hard to realize at cellular frequencies.
