Menlo Micro announced that it is sampling their MM51xx series of products. These new products, which operate at high power with ultra-low RF losses, and in a miniaturized surface-mount package, bring significant performance improvements as compared to electromechanical and solid-state RF switches. The MM5130 SP4T switch is designed to handle power levels up to 25W […]
Family of embedded antennas enable configurable IEEE 802.11ax connectivity
Airgain, Inc. announced the release of a toolkit of new embedded antennas solutions designed to provide enhanced performance and reduced time-to-market for Wi-Fi 6 wireless systems. The new antennas leverage Airgain’s over-the-air (OTA) performance validation and optimization, and already substantial expertise in Wi-Fi 6 system integration. In combination, these new products form a comprehensive toolkit […]
High-frequency integrated thin film band-pass filters come in ultraminiature packages
AVX Corporation introduced new 0805-case BP Series multilayer, integrated thin film (ITF) band-pass filters. Designed for broad compatibility with a wide range of high-frequency wireless applications, including mobile communications systems, satellite TV receivers, GPSs, vehicle-locating systems, and wireless LANs, the series is available in five frequency bands spanning 1,308MHz to 4,320MHz with 50Ω characteristic impedance, and is rated for […]
Inside look at a super-narrow band-pass filter-on-a-chip
The days of constructing bandpass filters from discrete components are pretty much over when it comes to the frequencies involved in modern wireless gear. That’s what makes the video we recently did with Alex Rabinovich from AVX interesting. Alex showed us a bandpass filter characteristic that’s super narrow, and the filter that creates also comes […]
High-impedance laminates help reduce antenna size
Rogers Corporation has introduced MAGTREX 555 Laminates, the first product in a new platform of high-impedance laminates featuring a high permeability and permittivity. These high-impedance laminates enable antenna designers to expand the trade-space of their antenna design enabling up to a factor of six reductions in size with minimal impact on bandwidth, up to a factor of […]
On-chip RF transformers could shrink thanks to rolled-up membrane design
Researchers at the University of Illinois say they have devised more efficient RF transformers by depositing conductors on a membrane that, once complete, rolls up to create a high-turns-ratio transformer. The transformers consist of two sets of rolled-up coils deposited on some kind of SiNx material. Researchers say they’ve used the technique to realize up […]
Bulk acoustic wave filters make life easier for Wi-Fi front-end designers
BAW filters help overcome the biggest challenges facing Wi-Fi front-end designs, including thermal management, interference, and RF linearity. Cees Links |Qorvo Wireless Connectivity Smart homes are getting smarter. So they increasingly make heavy demands on their internet routers, so much so that traffic demands are exceeding the capacity of the single-router model. Retailers and businesses […]
New laminates target base station antenna apps
Rogers Corporation has introduced two new products: AD300D laminates and IM Series laminates. AD300D fourth generation, commercial microwave and RF laminate material extends the capabilities of the successful AD300 product grade. This ceramic-filled, glass-reinforced, PTFE based material provides the controlled dielectric constant (2.94±0.05), low loss performance (0.0021 at 10GHz), very good passive intermodulation response (-159dBc […]
New E and W-Band PIN diode waveguide switches
Fairview Microwave Inc. has released a new line of E and W-band PIN diode waveguide switches. These single-pole single-throw (SPST) and single pole double-throw (SPDT) millimeter-wave waveguide switches offer an ultra-broadband frequency range with fast switching performance. They are ideal for telecommunications, test instrumentation, research and development programs and radar front ends in applications that involve […]
Signal-channel diversity and fading, Part 1: Space Diversity
In the engineering context, the phrase “channel diversity” refers to various techniques for getting a signal from point A to point B. The different approaches to diversity can be used individually or in combination. Q: What are the primary types of channel diversity in use? A: There are two primary types: space (spatial), and frequency. […]
