LDMOS RF Power-Amplifier Bias  
Controller  
DS1870  
General Description  
Features  
Two-Channel Solution for Programmable RF Bias  
The DS1870 is a dual-channel bias controller targeted  
toward class AB LDMOS RF power-amplifier applica-  
tions. It uses lookup tables (LUTs) to control 256-posi-  
tion 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 compensa-  
tion schemes that are not possible with conventional  
biasing solutions.  
Control  
The Potentiometer’s Position is Automatically  
Updated to Compensate for the Ambient  
Temperature and the Drain Voltage or Current  
A Five-Channel, 13-Bit ADC Continuously  
Monitors the Ambient Temperature, V , V , I  
D D1,  
CC  
and I  
D2  
Hi/Lo Alarms for Each ADC Channel can Trigger a  
Fault Output  
Nonvolatile Memory for the Device Settings,  
Lookup Tables, and 32-Bytes of User Memory  
Applications  
I2C*-Compatible Serial Interface with Up to Eight  
Cellular Base Stations  
Medical Equipment  
Industrial Controls  
Devices on the Same Serial Bus
