MIPI announces RF standards for mobiles
January 18, 2012 // Peter Clarke
The MIPI Alliance, an industry organization that promotes interface specifications for mobile devices, has announced two specifications targeting the digital modem and the front-end radio. These are the DigRF v4 and the RFFE v1.10 specification.
The DigRF v4 interface supports HSPA+, LTE, Mobile WiMax, and existing 3GPP standards including 2.5G and 3.5G. DigRF v4 is based on the MIPI Alliance M-PHY physical layer specification. The specification enables a single, integrated Link between a baseband IC and RFICs, with options for additional RFICs and BBICs using separate links.
The RFFE v1.10 specification defines a standardized control architecture for RF front-end devices, and offers an approach for multi-mode, multi-band and multiple antenna configurations. It offers a method for controlling power amplifiers, low-noise amplifiers, filters, switches, power management modules, antenna tuners and sensors. It supports point-to-multipoint connectivity, controlling simple to complex RF systems.
Companies contributing to the development of the DigRF v4 Version 1.10 specification include: Arasan Chip Systems Inc., Cadence Design Systems Inc, Fujitsu, Intel, Motorola Mobility, Nokia, Panasonic, Research In Motion, ST-Ericsson and Synopsys.
Companies contributing to the development of the RFFE v1.10 specification include: Analog Devices, Fujitsu, Nokia, NXP, Panasonic, Peregrine Semiconductor, Qualcomm, RF Micro Devices, Skyworks Solutions, ST-Ericsson, Texas Instruments and WiSpry.

The SoCKIT evaluation kit is Arrow's latest development tool, featuring an Altera Cyclone V SoC with a dual-core ARM Cortex-A9 MPCore processor integrated within its 28nm FPGA fabric.
Altera SoCs allow embedded system developers to differentiate their end product with customized hardware and software, and extend the product lifecycle through hardware and software updates in the field. This month, Arrow Electronics is giving away five SoCKIT evaluation kits featuring Altera’s ARM-Based SoCs, worth €249 each, together with the free entrance to one of Arrow’s SoC workshops organized throughout Europe.
And the winners are...
In our previous reader offer, Freescale Semiconductor was giving away five IMX6Q, Sabre-lite kits, worth £128.06 each.
Lucky winners include Mr. X. Salada Sole from the UK, Mrs A. Peric from Germany, Mr Z. Janosy from Hungary, Mr D. Gacina from Croatia and Mr B. Boris from France. All should be receiving their packages soon. Let's wish them some interesting findings with their projects.
