RF Micro Devices Inc. has introduced two products targeting the mobile handset industry. The RF6460 front-end platform features an ultra-compact “converged” multi-band, multimode architecture (2G/2.5G/3G/4G) that delivers best-in-class efficiency, eases implementation, shrinks solution size, and reduces component placements compared with mode-specific and band-specific architectures, according to RF Micro. The RF716x dual-band (EGSM900/DCS1800 or GSM850/PCS1900) GSM/GPRS transmit modules meet the front-end requirements of emerging market handsets.

The RF6460 incorporates the RF6260 multiband, multimode PA module, the RF6360 ASM, and the RF6560 front-end power-management IC. The broadband, multimode characteristics of the RF6260 and the flexibility of the RF6560 deliver a scalable front-end solution that simultaneously supports the implementation of up to five WCDMA/HSPA+/LTE bands—three high bands and two low bands—and all four bands of GSM/GPRS/EDGE in 3G/4G multimode mobile devices. Mobile device manufacturers can implement most 3G/4G band and mode combinations simply by selecting the appropriate band-specific duplexers to place with the RF6460. The RF6460 converged front-end platform supports all major air interface standards in multimode devices, including GSM/GPRS, EDGE, CDMA, TD-SCDMA (3G), WCDMA/HSPA+ (3G), and LTE (4G).

The GSM/GPRS TxM in the RF716x family are class 12-compliant and feature two symmetrical (interchangeable) receive (Rx) ports for ease of routing during implementation. The devices include functionally identical TxMs with “mirrored” footprints, maximizing layout design flexibility and easing implementation across handset platforms. The devices come in compact (6.63- by 5.24- by 1.00-mm) packages and feature electrostatic discharge protection of 8 kV CD at the antenna port and 1 kV at all other pins.

The RF6460 is currently sampling to lead customers and platform providers. Broad market availability is expected in the second quarter. The RF7168 dual-band (EGSM900/DCS1800) TxM is the first available member of the RF716x family. It is available today. Other members of the family are expected to be available in March. All cost under $1.00 in quantities of 10,000.
