ANTENNAS MICROWAVE CIRCUITS AND RADAR CROSS SECTION ANALYSIS SOFTWARE Integrated 50 PRODUCTS Multi-output clock generators feature low jitter and flexible outputs Combining low-noise, low-jitter performance and signal output ﬂexibility, the AD9520 and AD9522 multi-output clock generators from Analog Devices include a 512-byte embedded EEPROM memory block, affording system engineers a programmable clock solution that can serve as both the source and system clock. By programming their own speciﬁc set of output conditions using the on-chip memory, designers can easily conﬁgure the AD9520/2 as the source clock to ensure initial processing functions are synchronized when the system is powered on or reset. Competing clock ICs require a separate source clock, which must be independently matched to the system processor or microcontroller in order to program the system clock chip, adding component count, cost and complexity to network line cards, wireless and broadband infrastructure, medical imaging, and data converter clocking designs. In addition to the on-chip EEPROM and PLL, the clock generators integrate dividers, fanout buffers, and a VCO INTEGRATED’s tools provide solutions to a wide variety of electromagnetic field models, which can be obtained based on the Method of Moments (MoM) approach for open region problems and Finite Element Method (FEM) for closed region problems. Fast. Accurate. Easy-to-use. • Link to CAD packages for true representation of complex geometric shapes • Powerful parametric solvers Other benefits: • Incorporated Physical Optics (PO) along with the Moment Method • Only tool in the market that handles Highly Lossy Materials • Built-in FFT solver, for electrically large problems • Accurate calculation of near field distribution • Field distribution with any arbitrary, free form geometry • Excellent match when comparing software results with experimental results that tunes from 1.4 GHz to 2.95 GHz. An external 3.3-V/5-V VCO/VCXO of up to 2.4 GHz can also be used. The PLL/VCO clock-generation circuitry boasts leading phase noise of -150dBc/Hz at a 10 kHz offset on a 200-MHz clock signal, while the clock distribution fanout channels feature ultra-low wideband jitter performance of 225 femtoseconds. Two reference inputs allow glitch-free switchover for applications requiring redundant references, while a PLL holdover mode maintains the output frequency in the event of a lost reference signal. Zero delay operation is available to ensure precise phase alignment between inputs and outputs. EuMW 2008 Exhibitor: Stand 1005 www.mwee.com/210604658 Medium power amplifier high gain and low consumption over DC to 2.8 GHz Mimix Broadband has introduced the CGB8001-SC 5-V InGaP HBT ampliﬁer which combines medium power and high gain with low power consumption. It consumes 100 mA of current and covers DC to 2.8 GHz frequency bands with 27 dBm P1dB and 15.5 dB gain at 2.1 GHz. Designed for 5 V applications, the ampliﬁer is suitable for high linearity transmit, receive and IF applications, including CATV, 3G, WiBro and WiMAX. The low current consumption and high linear performance under complex modulation makes it an ideal output stage for multicarrier applications. The ampliﬁer is offered in an industry standard, RoHS compliant, SOT-89 package and includes an integrated active bias circuit and ESD protection, signiﬁcantly enhancing quality, reliability and ruggedness. The integrated active bias circuit minimizes performance variation over temperature and enables direct operation from +5 V supply EuMW 2008 Exhibitor: Stand 1406 www.mwee.com/210605223 TRY OUR SOFTWARE FOR 30 DAYS!
