Abstract
This paper describes a single-carrier UHF linear power amplifier for use in GSM-EDGE base station applications. The amplifier employs a sophisticated digital predistortion linearisation system as a method of improving both efficiency and signal vector error (SVE), whilst maintaining a relatively simple architecture. A key benefit of the technique is that it provides an RF input/output interface without the requirement for a local oscillator, which is traditionally required when employing a digital lineariser in an RF amplifier.
