5G mmWave signal chain: the phase-locked loop
In “Look inside the 5G mmWave signal chain,” we explored the overall architecture of the mmWave signal chain. Now, we’ll look deeper into each of a transceiver’s components. Phase-locked Loops (PLL) are important blocks for a clean reference clock generation in cellular networks. In 5G mmWave radio networks, the PLL supports data rates of 1…
