SUNNYVALE, Calif.-Philips Semiconductors announced a new Time Division Multiple Access radio-frequency chipset targeted for designers of dual-band TDMA cellular and personal communications services handsets.
The chipset reduces the number of components needed to build a dual-band RF system by half, said Philips.
The SA1920 RF receiver front-end, the SA 647 digital IF receiver and the SA9025 transmit modulator with fractional-N synthesizer comply with the TDMA Interim Standard 136 standard for dual-band, dual-mode operation.
