Applications
One chip, multiple LTE signals for 3G, 4G, and 5G macro cell TDD base station work
Matt Purvis from ADI recently took us through a demo of a super-wideband RF transceiver chip that targets the expanding 5G telecom area. The point of the chip is to transmit multi-carrier LTE signals and to simplify the task of designing MIMO systems. Called the ADRV9009, it is a single-chip time division duplex (TDD) design […]
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 […]
Active noise cancellation, Part 2: Implementation
Part 1 of this FAQ looked at the basic concept of active noise cancellation, how it might be implemented in principle using analog circuitry, and the harsh reality of actually providing the ANC function. Part 2 looks at modern ANC systems and how they function, as well as their practical issues. Q: Is ANC using […]

Piezo ceramic harsh environment speaker features extended frequency range
Announced today by ISL Products International Ltd the PZ-94 harsh environment piezoelectric loudspeaker for broad frequency range applications. Ultra-thin, small, and lightweight, the piezo ceramic loudspeaker may be driven by low power. The speaker reproduces voice in the frequency response range of 450 HZ to 20 kHZ, and is tested to MIL–STD–810, method 509.1 (salt fog). The PZ-94 loudspeaker system features a […]
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 […]
