3 Description
The AMC7908 is a highly integrated power-amplifier
(PA) monitor and control device capable of
temperature, current, and voltage supervision.
The AMC7908 bias controller is based around eight
digital-to-analog converters (DAC) 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 AMC7908 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 AMC7908 an excellent
choice as an all-in-one, bias control circuit for
the power amplifiers found in RF communication
systems. 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.
