RF Micro Devices expands power amplifier module series

A few days ago, leading the specialized radio frequency integrated circuit (RFIC) of application of wireless communication Supplier RFMicro Devices, Inc. Company introduces its PowerStar&reg of new generation with leading industry; Power amplifier (PA) Module series. The size of these two sections of new PowerStar PA module is 6x6x1.4 millimetre, reduce by more than 30% than the previous generation PowerStar PA module. These PA module has been lowered complicately, has simplified and designed the procedure, thus make mobile phone manufacturers accelerate the listing time of the mobile phone with abundant function. PowerStar PA module of RFMD of new most generation includes: • Use the direct I&Q modulator or small-scale signal to polarise and modulate four frequency band RF3158 (GSM/GPRS/EDGE)s optimized for linear EDGE specially • Four frequency band RF3166 (GSM/GPRS)s optimized for GSM/GPRS 12 rank specially . RF3158 and RF3166 also have integral battery voltage (VBATT) Tracking circuit, this circuit is first circuit which faces the standard PA module products of industry. But the battery voltage of automatic measurement and ramp voltage of the regulation of the monitoring circuit of battery voltage, so can prevent the cycle of power control from reaching the saturation in low battery voltage state. VBATT maximal to reduce in low battery voltage state appearing and can reduce transition effect of efficiency in tracking circuit. Before introducing integration VBATT tracing circuit engineering of RFMD, the ramp voltage of hand regulation that the mobile phone artificer must be in the software. Have shortened the mobile phone to design time, has guaranteed that can realize the strong and reliable characteristic under various working conditions with VBATT tracking circuit of RFMD. Heavy-duty, efficient RF3158 and RF3166 are the independent PA module with 50 ohms of importing and 50dB control limit. RF3158 can be in GSM/EDGE, GSM850, DCS and the intersection of PCS and handheld digital the intersection of honeycomb and apparatus and run on enlarge as final RF in the intersection of 1910MHz and other application of frequency band from 824MHz to and 915MHz Device. RF3166 can be in GSM850, EGSM900, DCS and PCS handheld digital honeycomb apparatus and running from 824MHz to 849MHz, regarded as the final RF amplifier other application of 1910MHz frequency band from 880MHz to 915MHz, from 1710MHz to 1785MHz and. At present, RFMD is producing RF3166 in batches, when lot-size is 10,000, the unit price of this device is 1.95 dollars. RF3158 is being sampled to the customer at present, it would be put into batch productino in the second quarter of 2005.
