The AFE10004 is a highly integrated, autonomous, power-amplifier (PA) precision analog front end (AFE) that includes four temperature compensation digital-to-analog converters (DACs), integrated EEPROM, and gate bias switches. The four DACs are programmed by four, independent, user-defined, temperature-to-voltage transfer functions stored in the internal EEPROM, allowing any temperature effects to be corrected without additional external circuitry. After start up, the device operates without intervention from a system controller to provide a complete system for setting and compensating bias voltages in control applications.

The AFE10004 has four gate bias outputs that are switched on and off through dedicated control pins. The gate bias switches are designed for fast response. In combination with the device PA_ON pin, this fast response enables correct power sequencing and protection of depletion-mode transistors, such as GaAs and GaN.

The function integration and wide operating temperature range make the AFE10004 an excellent choice as an all-in-one, autonomous bias control circuit for the power amplifiers found in RF systems. The flexible DAC output ranges and built-in sequencing features let the device be used as a biasing controller for a large variety of transistor technologies, such as LDMOS, GaAs, and GaN.
