The 5G vision of 10 Gb/s leads to performance and power consumption challenges in the mobile terminal receiver because 10 Gb/s requires 400 MHz bandwidth, faster baseband processing, and an increased number of component carriers and MIMO streams. The contribution of this paper is to estimate the impact from these physical layer requirements to the power consumption of main receiver components, including LNA, ADC and baseband processor with Turbo decoding, in a Direct Conversion Architecture. The estimate of power consumption results from a comprehensive survey of component performance evolution, and extrapolation hereof to estimate trends, and main challenges, towards 2030. According to our results, in 2020 the receiver power consumption exceeds 3 W, and is thus a challenge to be addressed. Assuming the performance evolution continues as observed in this work, the 5G receiver will be on par with the current LTE implementations in 2027 and thus consume less than 0.8 W.
