NEWPORT BEACH, Calif. - Conexant Systems Inc. here today announced a new series of radio-frequency integrated circuit subsystems, which form the receiver and transmitter of second- and third-generation code division multiple access (CDMA) digital cellular handsets.
"These RFIC subsystems are the first to be manufactured in our advanced silicon germanium (SiGe) process, which provides the lowest power consumption in their class," said Mohy Abdegany, vice president of Conexant's Wireless Communications Division.
The receive and transmit RFIC subsystems are designed to be used with Conexant's existing power amplifier modules, baseband analog processors with integrated codecs, and power management devices to form a complete radio for a dual-band, tri-mode CDMA handset.
The new RFIC family consists of four devices: the CX74002 transmit RFIC subsystem, which incorporates all transmit functions from in-phase and quadrature (I/Q) analog signal inputs to both PCS and cellular power amplifier RF driver outputs; the CX74001 BiCMOS receiver; the CX74004 SiGe Dual-Band LNA/Downconverter and the CX74005 Bipolar Variable Gain Amplifier (VGA)/I/Q Demodulator RFIC Subsystem.
Conexant said the subsystems support the entire spectrum of emerging global CDMA standards and provide an easy migration path from current cdmaOne (IS-95A/B) to 3Gwireless standards, including cdma2000 and wideband-CDMA (W-CDMA).
All four devices will be available in sample quantities by the end of June, with production volumes expected to be offered by September. Pricing information was not released.
