THREE DIMENSIONAL EM SOFTWARE FOR PCs   Sonnet Software Inc. Liverpool, NY Commercial three-dimensional (3D) electromagnetic (EM) software has become a key to rapid prototyping and design of high frequency components, systems and antennas. However, these software packages have been practically limited to UNIX workstations or supercomputer environments because...

A LOW NOISE FREQUENCY SYNTHESIZER FOR THE CELLULAR BAND   Program Test Sources Littleton, MA In mixed-signal automatic test equipment systems, which cost from $1 M to $2 M, broad coverage from 1 to 1000 MHz or even 1 to 3200 MHz is not a luxury since the system...

A SUBMINIATURE SMT CIRCUIT INSERTION COAXIAL RELAY RelComm Salisbury, MD A coaxial circuit insertion (bypass) function relay provides a cost-effective approach for high performance wireless communications equipment as well as automatic test equipment and a variety of test and monitoring instrumentation. The relay's switching function allows a circuit element...

LOW COST SUBSTRATES FOR HIGH SPEED, HIGH FREQUENCY, HIGH VOLUME PCBs Arlon Materials for Electronics Division Rancho Cucamonga, CA New substrate materials for high speed, high frequency commercial electronic circuits have been introduced. The 25N substrate materials for high volume commercial circuits feature many of the performance advantages of...

High Frequencies in High Places Claude M. Weil and Roger B. Marks 1997 International Microwave Symposium Chair and Vice Chair Don't miss out on this year's Microwave Week to be held in the Mile-high city of Denver on June 8-13! This year's event, which includes the 1997 IEEE MTT-S...

Microwaves in the Mile-High City The 1997 MTT-S International Microwave Symposium (IMS) and Exhibition in Denver is scheduled to dazzle attendees while making its long-awaited return to Colorado following a 24-year hiatus. After setting an all-time attendance record in San Francisco in 1996, the event is poised for a...

New Types of Microstrip Antennas for the Applications Typically, patch antennas are narrowband and their Q factor is inversely proportional to frequency. The main reason for the high Q factor is that patch antennas are essentially circuits printed on a relatively thin substrate: the higher the dielectric, the higher...

Static Fractional: The True Fractional Division Method of Indirect Synthesis A significant development of the indirect frequency synthesis method, called fractional-N, has been developed recently. This article shows that this dynamic method is only one of two possible ways for the implementation of the fractional division idea. The second...
