MAXIM DS1870 Manual

Update: 30 September, 2023

DS1870 is a dual-channel bias controller for AB class LDMOS RF power amplifier applications. It controls the 256 positions of the potentiometer through look-up table (LUT) based on the amplifier temperature, drain voltage or drain current (or other external monitoring signals). DS1870 has internal temperature sensor and multi-channel A/D converters (ADCs) to provide a cost-effective solution, using nonlinear compensation techniques to improve power amplifier efficiency, which traditional bias solutions cannot provide.
