3 Description
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 builtin
sequencing features let the device be used as
a biasing controller for a large variety of transistor
technologies, such as LDMOS, GaAs, and GaN.
