RF6001
FRACTIONAL-N RF SYNTHESIZER WITH
MODULATOR AND DIGITAL IF FILTER
The RF6001 is a combination synthesizer and signal processing 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 synthesizer offers numerous fea-
tures including a fully digital GMSK modulator with provisions for an analog I/Q
interface and extremely low current consumption. The signal processor section pro-
vides 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 configured for either analog or digital operation.
Chip functionality is controlled through a three-wire serial data interface (SDI) bus.
The RF2722 is part of the POLARISTM TOTAL RADIOTM solution.
