The AFE20408 is a highly integrated power-amplifier (PA) monitor and control device capable of temperature, current, and voltage supervision.

The AFE20408 bias controller is based around eight digital-to-analog converters (DACs) with programmable output ranges. The eight gate bias outputs are switched on and off through dedicated control pins. The gate bias switches are designed for fast response and enable correct power sequencing and protection of depletion-mode transistors, such as GaAs and GaN.

The AFE20408 supervisor is based around an accurate multichannel analog-to-digital converter (ADC). The device integrates two high-voltage inputs, two high-side current-sense amplifiers and an accurate on-chip temperature sensor.

The function integration and wide operating temperature range make the AFE20408 an excellent choice as an all-in-one, bias control circuit for power amplifiers. 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.
