FRACTIONAL-N RF SYNTHESIZER WITH
MODULATOR AND DIGITAL IF FILTER
Part of the POLARIS^TM TOTAL RADIO^TM Solution
• Multi-Band EDGE_RX Handsets
• Multi-Band GPRS Handsets
Product Description
The RF6001 is a combination synthesizer and signal pro-
cessing IC, which along with the RF2722 Very-Low-IF
Receive IC, constitutes RFMD's low-cost GSM trans-
ceiver solution. The high-performance fractional-N syn-
thesizer offers numerous features including a fully digital
GMSK modulator with provisions for an analog I/Q inter-
face and extremely low current consumption. The signal
processor section provides a digital receive filter path
designed to complement the RF2722. The IF inputs are
digitized, filtered and downconverted to baseband I and Q
signals. The flexible baseband interface can be config-
ured for either analog or digital operation. Chip functional-
ity is controlled through a three-wire serial data interface
(SDI) bus. The RF2722 is part of the POLARIS^TM TOTAL
RADIO^TM solution.
