DS1870 - LDMOS RF Power-Amplifier Bias Controller

DS1870 Description

Rev 1; 5/04 www.DataSheet4U.com LDMOS RF Power-Amplifier Bias Controller General .
Features. Two-Channel Solution for Programmable RF Bias Control. The Potentiometer’s Position is Automatically Updated to Compensate.

DS1870 Features

* Two-Channel Solution for Programmable RF Bias 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, VCC, VD, ID1,

DS1870 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 i
