Choose a 5G base station’s PA bias control circuit

Ritesh Jain, Pratik Kalyanasundaram, and Himanshu Khatri, Renesas Electronics — Wed, 03 Apr 2024 09:48:19 +0000

Bias control of PAs is crucial to ensure optimum radio performance under all conditions. Current sensing and temperature sensing provide 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…
