RF Micro Devices Intros RF3158/RF3166 PA Modules
RF Micro Devices Inc. (RFMD, Greensboro, NC), a provider of proprietary radio frequency integrated circuits for wireless communications applications, introduced its PowerStar® power amplifier (PA) module portfolio. The two new PowerStar PA modules measure 6 mm x 6 mm x 1.4 mm and represent greater than 30% reduction in size versus the previous generation of PowerStar PA modules.
The RF3158 and RF3166 feature integrated battery voltage tracking circuitry, which automatically measures battery voltage and adjusts ramp voltage, preventing the power control loop from reaching saturation during low-voltage battery conditions. The high-power, high-efficiency RF3158 and RF3166 are self-contained PA modules with 50 &Omeha; input and over 50 dB of control range. The RF3158 is designed for use as the final RF amplifier in GSM/EDGE, GSM850, DCS and PCS hand-held digital cellular equipment and other applications operating in the 824 MHz to 915 MHz and 1,710 MHz to 1,910 MHz bands. The RF3166 is designed for use as the final RF amplifier in GSM850, EGSM900, DCS and PCS hand-held digital cellular equipment and other applications operating in the 824 MHz to 849 MHz, 880 MHz to 915 MHz, 1,710 MHz to 1,785 MHz and 1,850 MHz to 1,910 MHz bands.
The RF3166 is in mass production now and is priced at $1.95 in quantities of 10,000 units. The RF3158 is currently being sampled to customers and will ramp into mass production in the second quarter of calendar year 2005.
