Freescale Semiconductor has developed a programming method that reduces time to first call by up to 66 percent when developing new phones. The method uses single-command programming that reduces calibration steps and practically guarantees system compliance.

"Through embedding RF intelligence into the transceiver, we have witnessed unprecedented shortening of time to first call," said Kent Heath, director of cellular operations for radio products division (RPD). "Achieving time-to-first-call status in less time and fewer resources is possible today primarily because we are taking generations of RF experience and embedding that knowledge into the transceiver."

In traditional programming of the baseband to control the RF transceiver, an engineer would need to consider all the critical timing between the transceiver, power amplifiers, switches, low noise amplifiers, baseband processor and voltage regulators. The digital baseband must perform many calibrations to control a transceiver and the detailed timing of all transceiver functions. This interaction results in significant time investment to complete phone development successfully.

With Freescale's approach, an engineer enters a single command stating the desired channel and power level. This command sets the parameters and times the events such that system compliance is virtually assured.

"This is just one of the reasons our RF technology has been designed into some of the hottest devices on the market today," said Klaus Buehring, vice president and general manager of Freescale's RPD. "Our products that incorporate innovative design techniques like smart RF, have leading OEMs bringing phones to market more quickly and efficiently."

Freescale launched RFX275-20 RF subsystem as a 3G WCDMA/EDGE chipset, the 'first' to begin using the programming technique, but newer generations sampling soon are engineered to go even further in simplifying the layer-one programming.
