Abstract

This paper presents a low power and low group delay for multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) power amplifier (PA) for 3.1-7.5 GHz is proposed. The proposed PA employs a common gate with current-reused structure to provide wideband input matching, low group delay and low power consumption. The simulation results shows that the proposed PA design has an average gain of 11.4 dB with flatness of ±0.8 dB, while maintaining bandwidth of 2.6 to 8.3 GHz. An input return loss (S 11) less than -11.1 dB and output return loss (S 22) less than -10.5 dB, respectively are obtained. The PA design achieves the phase linearity (i.e. group delay) of ±67.1 ps and only consuming 14.5 mW power from 1.2 V supply voltage. A good output 1-dB compression point OP 1dB of 0.5 dBm is obtained.
