Hittite Microwave Corp. has introduced its 24th product line, Power Conditioning, ideal for low noise voltage regulation in automotive telematics, cellular/4G, WiMAX/4G, military and test equipment applications.
Rohde & Schwarz:R&S ZVAX24 Hardware Extension Unit The new R&S ZVAX24 hardware extension unit converts the vector network analyzers of the R&S(r) ZVA family into space saving solutions to make intermodulation or pulse profile measurements easier. Even applications up to +43 dBm can be performed with no problem.
Reactel Inc.:Terminated Diplexer 2DMPX-102-N11 Reactel part number 2DMPX-102-N11 is a terminated diplexer. This unit exhibits superior VSWR performance in both the passband (120 to 1000 MHz) and reject band (20 to 100 MHz). This high power unit offers 0.7 dB of insertion loss and greater than 70 dB of rejection.
Freescale Semiconductor Inc.:InGaP HBT MMG3014 The MMG3014NT1 is a 40 to 4000 MHz general purpose amplifier that is internally input matched and internally output prematched. It is designed for a broad range of Class A, small-signal, high linearity, general purpose applications.
RFMD®:RF3021 SPDT Switch Designed for general purpose switching applications which require low insertion loss and high power handling capability, the RF3021 is ideally suited for battery operated applications requiring low insertion loss and switching with very low DC power consumption. The switch also features low control voltage and moderate isolation.
Carlisle Interconnect Technologies:HDRFI(r) Mixed Signal Circular Connector The HDRFI(r) Circular connector family is comprised of insert arrangements that maximize the number of size 16 RF contacts available in a standard circular connector arrangement. The product line encompasses shell sizes 15 to 25 and is based on the D38999 Series III specification.
Aeroflex/Weinschel Inc.:6 GHz Programmable Attenuators Aeroflex/Weinschel offers a series of 6 GHz relay switched programmable attenuators which are specifically designed for Wireless/Cellular, RF Simulation/Emulation & Communication Test Applications. This series is available in many standard attenuation ranges and cell configurations (0 to 55/1 dB, 0 to 103/1 dB and 0 to 55.75/0.25 dB).
Jim Rautio, Founder of Sonnet Software, talks about the humble beginnings of his company, converting microwave and high-speed engineers into EM believers, and why EM software always gives the wrong answer
Len Crane, Technical Marketing Manager at Coilcraft, has over 30 years of inductor design experience. He talks about a new interactive online inductor selection tool that helps engineers compare inductors and their critical performance data such as Q, equivalent series resistance and self-resonant frequency.
Agilent's ADS 2010, now supports IBIS-AMI, a modeling standard for SerDes transceivers used in high-speed serial links. The company has been working with a number of leading IC vendors to support this open standard, replacing proprietary encrypted models with models that also can be written at the behavioral level, allowing them to run significantly faster.
The new features in IVCAD from Amcad helps RF test engineers perform advanced characterization such as pulsed IV, pulsed S parameter and load pull measurement OF RF semiconductor device. In addition, it includes transistor equivalent circuit model extraction tools and circuit behavioral modeling plug-in.
