Product Details

General Description

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 amplifierâ€™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 amplifierâ€™s efficiency by using nonlinear compensation schemes that are not possible with conventional biasing solutions.

Features

â™¦ Two-Channel Solution for Programmable RF Bias Control
â™¦ The Potentiometerâ€™s Position is Automatically Updated to Compensate for the Ambient Temperature and the Drain Voltage or Current
â™¦ A Five-Channel, 13-Bit ADC Continuously Monitors the Ambient Temperature, VCC, VD, ID1, and ID2
â™¦ Hi/Lo Alarms for Each ADC Channel can Trigger a Fault Output
â™¦ Nonvolatile Memory for the Device Settings, Lookup Tables, and 32-Bytes of User Memory
â™¦ I2C*-Compatible Serial Interface with Up to Eight Devices on the Same Serial Bus
â™¦ Single 5V Power Supply
â™¦ Small 16-Pin TSSOP Package
â™¦ -40Â°C to +95Â°C Operational Temperature Range

Applications

Cellular Base Stations
Medical Equipment
Industrial Controls
Optical Transceivers
