NEWPORT BEACH, Calif.-Rockwell Semiconductor Systems last week introduced its first chipset using Code Division Multiple Access technology.
The chipset is an integrated radio-frequency subsystem for CDMA that also supports Advanced Mobile Phone Service analog cellular phones. The chipset can be used in single-mode CDMA applications, dual-mode CDMA/AMPS applications and tri-mode applications with CDMA operating in either cellular or personal communications services frequencies.
“Expansion into the CDMA market with a dual-band, multimode radio subsystem solution is a logical next step for Rockwell,” said Vijay Parikh, vice president and general manager for Rockwell’s Wireless Communications Division.
The three-device chipset includes the RF250 receiver, the RF251 transmitter and the RF252 CDMA baseband analog processor. The RF250 includes two low-noise amplifiers, one for 800 MHz operation and one to support 1900 MHz operation. The 1900 MHz LNA also can be configured for Korean PCS frequencies.
The chipset is priced at $35 in quantities of 10,000 units, said the company.
