A Low Cost Millimeter-wave Receiver Communication Solutions Inc. Baltimore, MD A low cost millimeter-wave receiver intended for military satellite communications (MILSATCOM) downlink or terrestrial microwave link monitoring applications has been developed. This new receiver represents a major breakthrough in lowering the cost per gigahertz of this type of receiver....

8 to 15 GHz High Spectral Purity PLDROs for LMDS and MVDS Applications Nexyn Corp. Sunnyvale, CA Local multipoint distribution systems (LMDS) and multipoint video distribution systems (MVDS) are paving the way for future telecommunication services by offering expanded channels and enormous data rates. LMDS and MVDS transmitters use...

Low Cost, Ultra-high Isolation SPDT Switches Mini-Circuits Brooklyn, NY Wideband test instrumentation often requires signal routing. This function is usually accomplished with mechanical switches, which are expensive and slow. When isolation requirements are not high, electronic switches may be utilized. However, most high isolation electronic switches available in today's...

Parametrics and Optimization Using Ansoft HFSS Ansoft Corp. Pittsburgh, PA The high frequency structure simulator (HFSS) is widely recognized as the tool that brought the power of the finite element method to three-dimensional (3-D) RF and microwave design. Finite element analysis allows complicated 3-D structures such as transitions, filters,...

Thermal Overdrive Firmware to Improve Thermal Test and Conditioning Throughput Sigma Systems Corp. San Diego, CA Thermal testing and conditioning involve moving heat. Moving heat into or out of a device under test (DUT) takes time. That time affects production throughput and, ultimately, production cost. However, there are methods...

Modular Design of Power Amplifiers Anaren Microwave Inc. E. Syracuse, NY Power amplifier designers today face increased peak power-handling requirements due to the new digital modulation forms used in wideband CDMA (W-CDMA) systems. At the same time, the power amplifiers must meet stricter linearity requirements and the available RF/microwave...

Nonlinear Waveform Prediction in Fast Microwave Circuits Optotek Ltd. Kanata, Ontario, Canada MMICAD WAVEFORM,™ a new time domain, transient analysis simulator, allows the prediction of waveforms in strongly nonlinear circuits in which accurate S-parameter data can be imported and used in the simulation. The new time domain software is...
