Using Calibration to Optimize Performance in Crucial Measurements
The following booth numbers are complete as of March 18, 2010.
This L-band polarizer sets a new standard for air-cooled ferrite control devices required to operate at high average power levels. Capable of switching between vertical linear and right-hand circular polarization, the L-band polarizer handles 65 kW peak and 6.5 kW average power. Maximum insertion loss is 0.4 dB, with 500 microseconds switching between states. The L-band polarizer allows the FAA LRR to switch between polarization modes dependent on weather conditions, providing feedback indicating the proper moment for switching.

QFN Packaged Up-converter
This 5.6 to 10.5 GHz GaAs MMIC up-converter integrates a double-balanced image reject mixer, LO buffer amplifier, RF buffer amplifier and variable attenuator, all within a fully molded 4×4 mm QFN package. This RoHS-compliant, packaged up-converter has an output third- order intercept point (OIP3) of +25 dBm, a conversion gain of 8 dB and a typical image rejection of 15 dBc. Variable gain regulation can be achieved by adjusting the bias, with turn-down trajectories optimized to maintain linearity and minimal 2xLO leakage over the gain control range. The XU1012-QH is well suited for point-to-point (PTP) radio, LMDS, SATCOM and VSAT applications. The XU1012-QH is one hundred percent RF and DC tested.
Mimix Broadband Inc.
5 to 20 GHz Wideband Microwave Amplifier
The Mini-Circuits AVA-24+ is a surface-mount, microwave amplifier and fully integrated gain block up to 20 GHz. It is packaged in Mini-Circuits’ industry standard 3×3 mm MCLP (QFN) package, which provides excellent RF and thermal performance. The AVA-24+ integrates the entire matching network with the majority of the bias circuit inside the package, reducing the need for complicated external circuits. This approach makes the AVA-24+ extremely flexible and enables simple, straightforward use.

The Modelithics COMPLETE Library v7.0 encompasses all passive and active Modelithics models available for designers using Agilent Technologies’ ADS. Modelithics COMPLETE Library versions for AWR Microwave Office and Agilent Genesys are scheduled for release by June. Increased flexibility is also available with the company’s multi-simulator option for customers using multiple EDA tools. Get more information or a free trial at firstname.lastname@example.org.
Momentive Performance Materials’ is a leader in thermal management products. Momentive’s thermally annealed pyrolytic graphite (TPG) has thermal conductivity over four times that of copper, yet is only 1/4th the weight of copper. The ever increasing power consumption of microelectronics demands more advanced technologies and materials. TPG provides new solutions to thermal problems in many aerospace and military applications, including radars, satellites and fighter jets. Ongoing programs are designed to translate this success to broader commercial markets.

Ku-band Block Up Converter
Narda is capitalizing on its Ultimate SMTSM Technology to produce low cost BUC/BDC modules for X-, Ku- and Ka-band SATCOM applications. These complex integrated microwave assemblies (IMA) are constructed using a single multilayer board with the microwave circuitry on the top side and the control circuitry on the bottom. Connections from top to bottom are made with via holes as appropriate. These vias combined with a novel sub cover approach meet required high isolation levels.

EM Supreme Version 2010
PedaSoft LLC announced EM-Supreme Version 2010. EM-Supreme is a time-domain Field-Device-Circuit Co-simulator that can be used to model passive structures, active components, and complete RF and millimeter-wave modules. EM-Supreme is an accurate alternative to what RF designers are using today “i.e. modeling the active and passive parts of the chip using separate field and circuit simulators, followed by combining the results employing simple approximations, without taking the effect of electromagnetic coupling, radiation, and interference into consideration,” which leads to inaccurate models especially at high power and/or high frequency RF chips. With EM-Supreme, RF designers can model CMOS as well as GaAs and GaN FETs. The tool enables RF designers achieving first-pass design success, eliminating ad-hoc design, and reducing time-to-market and development cost.
