Understanding the U.S. Public Safety Network and MCV Microwave’s Role in Enhancing Reliability
The U.S. public safety telecommunications network is an essential system that allows first responders—such as police, fire, and medical services—to communicate reliably and efficiently during critical situations. Ensuring this communication network functions seamlessly under all conditions is vital for public safety. Below, we explore the frequency bands used in these networks, their requirements, the challenges they face, and how MCV Microwave plays a pivotal role in addressing these challenges through high-quality, custom solutions.
Troubleshooting for Interferences in 5G Networks
This white paper addresses the growing concerns of Passive Intermodulation (PIM) and other forms of interference in 5G networks. It explores the unique challenges introduced by new frequency bands and highlights effective strategies for troubleshooting these issues. The paper reviews current industry trends in PIM detection and discusses MCV’s innovative solutions tailored for Radio Frequency Maintenance Engineers.
5G C-Band Interference Mitigation: By Edward Liang, PhD, MCV-Microwave
Fabs and Labs: MCV Microwave
In 1995, two Ph.D.’s were inspired to commercialize high Q, low loss dielectric materials, the fruits of research at the College of Engineering & Applied Sciences at Stony Brook University on Long Island. They formed MCV Microwave, with MCV an acronym for the pillars of the new company: materials, customer centric and vertically integrated.
LC Filters for Aerospace and Defense
For demanding aerospace and defense applications, MCV Microwave offers an extensive line of LC filters in surface-mount, drop-in and “connectorized” packages that withstand rugged environments. LC filter configurations comprise lowpass, highpass, bandpass, band reject, duplexers, multiplexers and tunable filters, with center frequencies from 100 kHz to 10 GHz.
Three Filter Families for Wireless Infrastructure – Ultra-Low PIM and Cavity Filters
MCV Microwave has developed three new filter families for wireless infrastructure. The first is a line of ultra-low passive intermodulation (PIM) cavity filters and multiplexers covering the TETRA and all LTE frequency bands from 300 to 3600 MHz. The typical production PIM performance is −163 dBc, measured with two CW tones, each at 43 dBm. An even lower PIM filter line with a guaranteed −173 dBc is available for PIM test bench and more demanding testing applications.
Novel Wideband Frequency Selective Surface Filters with Fractal Elements
High performance frequency selective surface (FSS) filters have a myriad of applications in the field of 5G wireless communication and antenna/radome systems. The most common FSS is a two-dimensional (2D) periodic array of thin conducting or aperture (also termed slot) elements etched on a flat or curved dielectric structure. This type of structure usually exhibits frequency filtering characteristics similar to the frequency filters in traditional RF circuits.
Ultra-Low PIM Cavity Filters
MCV Microwave has developed a line of ultra-low passive intermodulation (PIM) cavity filters and multiplexers covering frequency bands from 250 MHz to 6 GHz. The typical PIM performance in production is -163 dBc measured with two CW tones, each at 43 dBm. An even lower PIM filter with a maximum of -168 dBc is available, if requested.
Characterization and Modeling of High Q Dielectric Resonators
This article addresses the practical issues using high Q dielectric resonator (DR) cavity designs for RF/microwave oscillators. DR materials and basic cavity structures are described, along with the characterization and measurement of cavity Q. The complex resonant modes and coupling structures are detailed, with special emphasis on the impact of coupling and tuning structures on various resonant modes.
Ultra-Narrowed Cavity Filters to Ku-Band
MCV Microwave offers high performance ultra-narrowband cavity filters and duplexers covering frequencies up to 13 GHz. Typically, cavity filters are known for low insertion loss, tight frequency selectivity and broad spectrum rejection. MCV Microwave’s dielectric loaded, cavity bandpass filters and duplexers — BCCD and DCCD series, respectively — bring these desirable performance characteristics to a new height for the microwave engineering community.
