Microwave subsystems are complicated and have many tradeoffs in design. This is especially true with RF filter products. To help engineers navigate RF filter procurement, Q Microwave has created this comprehensive guide covering RF filter materials, configurations and packaging. This eBook reviews filter design, material selection, packaging, SWaP-C, and customization to meet unique needs.
This eBook addresses some of the challenges and best practices when designing and fabricating PCBs for RF applications. The first article gives a good overview of the fabrication process for a variety of different multilayer printed circuit boards. The second article provides insight into the reality of PCB fabrication versus the ideal models and how those differences become more important as circuits go higher in frequency. Article three acknowledges that these PCBs will operate at elevated temperatures, and it provides insight into the failure mechanisms, test methods and proper selection of substrate materials to optimize temperature performance. The fourth article provides good technical details about how to select the proper circuit board dielectric mate-rial as applications go higher in frequency. The final two articles address the finer points of the board design and manufacturing process for a microwave power amplifier and a microwave/millimeter wave patch antenna.
This paper explores the implementation of Mini-Circuits’ BFHK-series high-rejection LTCC filters in a coplanar waveguide (CPW) environment using a novel interposer board and related effects on filter rejection. Real test data from a leading customer’s evaluation of these filters in a channelized housing is presented demonstrating comparable rejection performance to that of stripline implementations in the range of 70 to 90 dB.
This application note provides a short technical introduction to voltage controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.
Radiofrequency engineers and microwave/mmWave antenna designers are often limited by the strict constraints of traditional antenna manufacturing methods, leading to compromised performance, reduced innovation, or ballooning costs. Fortify’s innovative additive manufacturing technology has unlocked possibilities, design freedoms, and more powerful antenna systems across a wide range of antenna applications. This RF applications guide presents nine ways that 3D-printed dielectrics will transform and enhance your antenna design.
Operating within the 8.0–12.0 GHz frequency range, X-Band radar systems have proved vital across various industries, including meteorology, air traffic control, defense, and maritime services. Their exceptional resolution and accuracy make them indispensable in our technology-driven world.
Phased array, and more specifically Active Electronically Scanned Array (AESA) technology has been in use for several decades. This type of array uses active components to control the phase and amplitude weighting of individual elements or groups of elements to modify the array’s aperture distribution.
Digital filters provide a meaningful way of controlling the input spectra of communication systems over a wide range of applications. They can filter harmonics or isolate frequency bands to prevent intersymbol interference while saving you from the hassle of part procurement, PCB layout, and variations that come with their analog counterpart.
As wireless applications grow, the needs for spectrum monitoring and interference hunting grow with them. In some applications, interference can be life-threatening. Portable spectrum analyzers are invaluable interference hunting tools.
The need to address EMC/EMI problems has never been more pressing. As electronic devices become smaller, faster, and more powerful, the potential for interference grows exponentially. It's no longer sufficient to simply design and build electronic systems without considering their EMC/EMI characteristics. Engineers, designers, and technicians must proactively identify and mitigate these issues to ensure that their products meet regulatory standards, perform reliably, and avoid costly setbacks. This eBook provides an understanding of the underlying principles, practical methodologies, and advanced techniques for dealing with EMC/EMI challenges. It is designed for both newcomers seeking a foundational knowledge of the subject and experienced professionals looking to deepen their expertise.
