CXA3003R
Baseband analog processing IC for dual-mode CDMA/FM cellular phone
For the availability of this product, please contact the sales office.
Description
The CXA3003R is a baseband analog processing
IC for dual-mode CDMA/FM cellular phone. The
CXA3003R interfaces between the inter-frequency
section and the digital processing circuitry of the
telephone. The receive circuit functions primarily
convert analog IF signals to the analog baseband
frequency range and to convert the analog
baseband signals into digital signals. Transmit
circuits convert digital data into analog baseband
signals which are then up-convert to the IF
frequency range.
