Vishay Siliconix Releases New 20-V and 30-VP-Channel Power MOSFETs With Industry’s Lowest On-ResistanceThe devices will be used as the adaptor switch and for load switching applications in notebook computers and industrial/general systems. Adaptor switches (switching between the adaptor/wall power and the battery power) are always on and drawing current. The lower on-resistance of the Si7135DP and Si7633DP translates into lower power consumption, saving power and prolonging battery life between charges. [Read more...] |
Highly Integrated RFIC is ideal for Cellular/3G Infrastructure!
Chelmsford, MA 10/27/06 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for communication & military markets, has introduced a new highly integrated, High IP3 Dual Downconverter RFIC which is designed for use in wireless infrastructure applications from 800 to 960 MHz, including those based on CDMA, WCDMA, GSM, GPRS and EDGE standards. The HMC581LP6(E) is a High IP3 Dual Channel RFIC Downconverter which is comprised of two identical downconverter channels including high IP3 mixers, and LO and IF amplifiers. The HMC581LP6(E) features high input IP3 of +26 dBm, high conversion gain of 9.5 dB, and low SSB noise figure of 13 dB. The passive mixer outputs and IF amplifier inputs are positioned so that an external IF filter can be placed in series between them. The single LO input of the HMC581LP6(E) requires only 0 dBm of LO drive, allowing both channels of the converter to be driven directly from a single synthesizer output. This highly integrated design supports IF frequencies from 50 to 300 MHz, while the wide LO frequency range of 700 to 1160 MHz supports low side and high side LO frequency plans. The HMC581LP6(E) requires no external baluns, is housed in a RoHS compliant leadless 6x6 mm QFN “E” SMT package, and shares a common pinout with the HMC581LP6(E), which covers similar applications from 1.7 to 2.2 GHz. Samples and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.
