MSM6250CHIPSET SOLUTION  
RFL6200 Device Description  
RFR6200 Device Description  
Integrated into the RFL6200 device are low-  
noise amplifiers (LNAs) for the UMTS  
bands, with three gain settings that are  
programmable through the serial bus  
interface (SBI).  
The RFR6200 device is the radioOne zero IF  
downconverter. The device has a mixer which,  
when combined with the RFL6200, provides full  
RF-to-baseband downconversion for UMTS  
bands. The LO generation for direct conversion is  
integrated on-chip.  
Operating modes — sleep, Receive (Rx), and Rx/Transmit (Tx)  
— as well as LNA bias currents are all automatically adjusted  
via software in order to minimize DC power consumption.  
Depending on handset status, the LNA bias current adjusts  
accordingly to meet RF performance requirements with  
minimal power consumption.  
Increase in standby time is achieved by selective circuit power down,  
gain control and bias current. These features, along with all of the  
radioOne chipset functions, are controlled by the MSM6250 chipset.  
The device is designed to operate with 2.7 to 3.1 V power supplies  
and is compatible with single-cell Li-Ion batteries.  
The device is fabricated using SiGe BiCMOS process, which is  
suited for high performance RF circuits. The RFL6200 is  
packaged in a very small 16-pin bump chip carrier (16  
BCCP).  
The RFR6200 device is fabricated using SiGe BiCMOS process, which  
provides high frequency, high precision analog circuits as well as low-  
power CMOS functions. Package type is 40 BCCP.
