The company freescale semiconductor presented, as it is asserted, the smallest in the world multi-range radio-frequency solution for mobile terminals 3G. New product support OF EDGE and UMTS. It is assumed that its tiny sizes will allow developers to additionally decrease the overall sizes and the cost of cell phones and other devices, designed for the work with networks mobile connection. The important special features of this solution are : the simplest in the world program model and digital interface, which satisfies the specifications of the open standard digRF.
Under designation RFX300-30 was hidden the collection of two microcircuits, which supports multi-mode and multi-line networks UMTS (9 ranges) and GSM/EDGE (four ranges). Here was realized the support of HSDPA (speed up to 7,2 Mbit/s) and HSUPA (up to 5,76 Mbit/s). According to the data of producer, RFX300-30 proposes the most complete coating of 13 ranges among analogous proposals commercially available. The radio-frequency subsystem is designed for the production on 90nm technology CMOS.
In the composition of RFX300-30 enters UMTS/EDGE- transceiver freescale MMM7210 and driver amplifier MMM6038. Together they contain the block of analog for signals processing , radio-frequency receiver and radio-frequency transmitter, driver amplifier, power circuit control and a number of passive components, usually mounted to the card additionally. The presence of the digital interface, executed on the open specifications, gives the possibility to designers to use with several subsystems, without worrying about the compatibility problems.
Are at present are accessible only test coupons RFX300-30. Mass deliveries must begin in the fourth quarter. Related Products :
