Infineon Technologies BGMC1210
Bias and control ICs for GaN and LDMOS Doherty PAs
Infineon bias and control ICs are used to bias radio-frequency power amplifiers by generating accurate voltages with high-precision DACs. The BGMC1210 is a bias and control IC for Power Amplifiers (PA). The device is optimized for Doherty PAs and biases up to 2 PAs with 4 DAC outputs per PA but can be used in any PA configuration. The DACs have a resolution of 12-bit and a current driving capability of 50 mA sourcing and 20 mA sinking. 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.
