Infineon Technologies Bias & Control IC Power Amplifiers
Infineon Technologies Bias and Control IC Power Amplifiers are used to bias radio-frequency power amplifiers by generating accurate voltages with high-precision DACs. In addition, Infineon Technologies Bias and Control IC Power Amplifiers support many functionalities to monitor the power amplifier voltages, currents, and temperature to keep the device in an ideal operating condition.
