5G software stack runs on small cell PHY SoC
Integrate a 5G Open RAN L1-L3 software stack into a small-cell design.
Choose a 5G base station’s PA bias control circuit
Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provides the feedback needed to control the PA bias. The choice of sensing and biasing circuits brings design trade-offs. 5G base station power amplifiers (PAs) need biasing using a separate bias controller to maintain optimum performance…
