33. Millimeter Wave Body Scanners Market: Past, Present, And Future 4/27/2021

    Full body scanners have become an important part of the security and threat detection toolkit around the world. This article discusses how, by making the right technical design and partnership choices, system integrators of these full body scanners can be more confident in offering commercially viable solutions for this fast growing market.

34. From Airport Terminal To Main Street: Keeping Public Spaces Safe 4/27/2021

    There are some technologies that have re-defined their categories and made game-changing improvements in their applications. And while these technologies generally emerge to solve a specific problem, we can suddenly envision the range of possibilities they create for similar problems in other settings. 

35. Contactless Fluid-Level Measurement Using A Reflectometer Chip 4/27/2021

    Fluid-level measurements can be accurately measured through the wall of a nonmetallic tank by placing an air-dielectric transmission line up against the side of the tank and sensing the RF impedance. This article provides an empirical design example that illustrates how a reflectometer device such as the Analog Devices ADL5920 can simplify the design.

36. Power-Up Phase Determinism Using Multichip Synchronization Features In Integrated Wideband DACs And ADCs 4/26/2021

    A successful MCS process has been demonstrated using four Analog Devices’ AD9081 MxFETM ICs as the backbone of the subarray. This work is pertinent to any multichannel system present in any phased array radar, electronic warfare, instrumentation, or 5G platform.

37. Clocking Wideband GSPS JESD204B ADCs 4/26/2021

    Although many clock solutions can potentially be chosen for use with these high frequency ADCs, those with sufficiently low phase noise for the bandwidth of interest and the ability to synchronize many ADCs offer the best solutions.

38. An Interview With Analog Devices Discussing RF Electronics For Phased Array Applications 4/26/2021

    Much of the early phased array work was developed for radar applications, so considering the evolution of radar antenna implementations provides good insight as to how the modern digital beamforming antennas were conceived. This article summarizes some of the routine inquiries that are scattered in various forms on the internet into a more comprehensive discussion.

39. Analog Devices’ ADF4371 Delivers Groundbreaking Low Phase Noise And Spur Performance 4/23/2021

    Further demands on quality of the local oscillator (LO) or clock used in communications or mixed signal systems have lead to additional increasing demands for frequency bandwidth, throughput, and dynamic range in communications systems. The ADF4371, a newly released integrated phase-locked loop (PLL) and voltage controlled oscillator (VCO), and the similar ADF4372, showcase Analog Devices’ efforts to address the needs of these demanding applications.

40. IC Integration Enables Flat-Panel Phased Array Antenna Design 4/22/2021

    Advances in semiconductor technology have enabled the proliferation of phased array antenna across the industry. This shift away from the mechanically steered antenna to the active electronically scanned antenna (AESA) began years ago in military applications, but has rapidly advanced more recently in satcom on-the-move and 5G communications.
