MAX11014
Description
The MAX11014/MAX11015 set and control bias conditions for dual MESFET power devices found in point-topoint munication and other microwave base stations. The MAX11014 integrates plete dual analog closed-loop drain-current controllers for Class A MESFET amplifier operation while the MAX11015 targets Class AB operation. Both devices integrate SRAM lookup tables (LUTs) that can be used to store temperature and drain-current pensation data. Each device includes dual high-side current-sense amplifiers to monitor the MESFET drain currents through the voltage drop across the sense resistors in the range of 0m V to 625m V. External diode-connected transistors monitor the MESFET temperatures while an internal temperature sensor measures the local die temperature of the MAX11014/MAX11015. The internal DAC sets the voltages across the current-sense resistors by controlling the GATE voltages. The internal 12bit SAR ADC digitizes internal and external temperature, internal DAC voltages,...
