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...

Antenna Systems for Polarization Diversity During the last couple of years, antennas for mobile networks have sprouted up like gladioli all over our downtown areas. For aesthetic reasons and due to the fact that it has become more expensive to acquire the rights to install antennas on buildings and...

SiGe MMICs and Flip-chip MICs for Low Cost Microwave Systems Recent progress in SiGe device technology has improved cutoff frequencies of these devices to beyond 200 GHz. Such high speed transistors fabricated on low cost Si substrates allow high levels of integration as well as the development of low...

Major Advances in Phased Arrays: Fast One This article is the first of a two-part series that describes the major accomplishments in phased arrays, and new-age MMIC ground-based and airborne arrays. Significant advances have been made in the last 35 years in the area of electronically steerable phase-phase scanned...
