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++).

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.

RFT6100 Device Description
The RFT6100 device is a direct conversion
chipset that integrates all the upconversion and
modulation functionality necessary for
CDMA-mode phones operating in cellular and
PCS bands. This transmit chip consists of two
sets of I/Q modulators, one for cellular and one
for the PCS band. The baseband I/Q input from the MSM directly
modulates the cellular or PCS carrier derived from the respective LO
generation circuit.
Both the cellular and PCS output drive their own VGA with a gain
control range of 85 dB. A final cellular driver amplifier provides a
modulated RF output.
To accommodate split-band and filtering, the PCS VGA drives two
output amplifiers that can be selected independently or
simultaneously via an input selectable switch. All RF outputs have
fully integrated 50-ohm matching networks. Integrated on the
RFT6100 is the receiver phase locked loop (PLL), the transmit
PLL and the entire transmit VCO including resonant components.
The VCO drives the LO generation block, which in turn generates
the required local-oscillator signal for all CDMA bands of
operation.
