DS1870 LDMOS RF Power-Amplifier Bias Controller

The DS1870 is a dual-channel bias controller targeted toward class AB LDMOS RF power-amplifier applications. It uses lookup tables (LUTs) to control 256-position potentiometers based on the amplifier's temperature and drain voltage or current (or other external monitored signal). With its internal temperature Sensor and multichannel A/D converter (ADC), the DS1870 provides a cost-effective solution that improves the amplifier's efficiency by using nonlinear compensation schemes that are not possible with conventional biasing solutions.
