Highlights
Infineon Bias & Control ICs are used to bias radio-frequency power amplifiers by generating accurate voltages with high-precision DACs. In addition they support a multitude of functionalities to monitor the power amplifier voltages, currents and temperature to keep the device in an ideal operating condition.
The DACs are organized in two groups with independent supplies and can be operated with positive and negative supply voltages in order to bias LDMOS and GaN transistors.
Infineon Bias & Control ICs incorporates integrated clamping switches and buffers, designed to enable rapid Time Division Duplex (TDD) operation. This comprehensive integration does not require external switch components, leading to significant savings in both cost and space. The embedded switches enable fast switching within a timeframe as short as <<1us.
Infineon Bias & Control ICs have an integrated 60V Analog-to-Digital Converter (ADC) for Power Amplifier (PA) current and voltage measurements. Moreover, external voltage dividers or separate ADC components are not required, resulting in simplifies the analog front-end.
Infineon Bias & Control ICs feature an integrated temperature sensor, which provides valuable temperature compensation. Also, the high-speed I3C serial interface ensures an efficient DAC setting.
