  Abstract

In this paper, an RF system architecture is proposed with a local oscillator (LO) without the phase locked loop (PLL) that requires high complexity, high power consumption, and external control signals. In order to use IoT sensor systems during a full battery life-cycle, compact, low-cost, and low-powered RF system should be designed. The reception baseband bandwidth is designed under consideration of frequency variation at an LO due to non-PLL configuration. Moreover, the complementary lowpass filter is designed. To evaluate the proposed system performance, the digital data is transmitted and recovered with good performance for the various LO frequency variation range such as temperature, and a co-channel interferer. The proposed non-PLL configuration is verified as an appropriate RF system architecture for compact and low-powered IoT sensor systems based on the presented design considerations.
