RFL6000 Device Description
Integrated into the RFL6000 device are two low
noise amplifiers (LNA): a cellular LNA and PCS
LNA.
Operating modes — Sleep, Rx and Rx/Tx — as well
as LNA bias currents, are all automatically adjusted
via software to minimize DC power consumption. Depending on
handset status, the LNA bias current adjusts automatically to meet RF
performance requirements with minimal power consumption.
The device is fabricated using a SiGe BiCMOS process, which is suited
for high performance RF circuits. The RFL6000 device is packaged in
a very small 16-pin bump chip carrier (16-pin BCC++).

• Fabricated in SiGe BiCMOS process
• Small package: 16-pin BCC++ (4 mm x 4 mm)
RFR6000 Device Description
The RFR6000 device is the radioOne ZIF down
converter. The device has three mixers which,
when combined with the RFL6000 device, provide
full RF-to-baseband down conversion for the
cellular, PCS and GPS band. The LO generation
block produces all LO signals so that only one
external single-band VCO is required for all CDMA frequency bands of
operation.
Included on chip is the GPS LNA as well as the entire GPS VCO
including resonant components. The Rx PLL, which resides on the
transmit companion IC, the transmit device, is switched between the
GPS VCO and the external Rx VCO.
Extension of standby time is achieved by selective circuit power-down,
gain control and bias current. These features along with all of radioOne
chipset functionalities are controlled by QUALCOMM's MSM device.
The device is designed to operate with 2.7 to 3.0 V power supplies
and is compatible with single-cell Li-Ion batteries. Compatibility to the
digital reference voltage (1.8 to 3.0 V) is assured when the VDDM is
connected to the MSM pad voltage.
The RFR6000 device is fabricated using a SiGe BiCMOS process,
which provides high-frequency, high-precision analog circuits as well
as low-power CMOS functions. Package type is a 40-pin BCC++,
which includes a large ground slug for improved grounding,
mechanical strength and thermal conductivity.
RFR6000 Device Features
• Compatibility with QUALCOMM's radioOne ZIF chipset eliminates
the entire IF, reducing component count and space

• Single- or multimode operation: cellular CDMA, PCS CDMA and
GPS
• Full downconversion — RF to baseband
• Receive path circuitry
– GPS LNA

– Baseband amplifiers with DC offset adjustment
• Only one single-band external VCO (Rx VCO) is needed for all
CDMA bands of operation for entire radioOne chipset
• Includes entire on-chip GPS VCO-including resonant circuit
• Individual circuit power on/off controls
• Power reduction feature control extends handset standby time
– Selective circuit power-down
– Gain and bias controls
• Low-power supply voltage (2.7 to 3.0 V), low-power dissipation
– Digital reference voltage is compatible with lower MSM voltage
(1.8 to 3.0 Vdd)
• Available in small, thermally efficient package (40-pin BCC++)
