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…

Renesas adds three timing ICs for 4G/5G radios
The 8V19N850 radio synchronizer and 8V19N880/8V19N882 jitter attenuators enhance a radio unit’s timing capabilities.
5G needs better amplifier efficiency
Power amplifier efficiency too center stage at the 2020 International Microwave Symposium’s 5G Summit. In this video interview, Naveen Yanduru of Renesas, one of the summit’s presenters, explains why engineers need to continue working on the problem.
IMS 5G Summit: Design challenges remain (part 1)
Just because 5G is rapidly rolling out doesn’t mean everything works and it’s time to move on. Indeed, the design challenges are just beginning, as this two-part series from IMS 2020’s 5G Summit shows.
