There is more to selecting an inductor than the nominal inductance value. To ensure your choice will perform in your application, you need to give careful consideration to inductance tolerance, current ratings, DCR, operating temperature and efficiency under specific conditions. This paper provides students and anyone new to inductors with an overview of the key performance ratings they will need to understand when specifying RF and Power Inductors.
Radio Frequency (RF) Filters are necessary for filtering out unwanted signals from equipment such as wireless and satellite communications, radar and broadcasting applications and transmit and receive modules. This paper explores filter topologies, effectiveness of the filters and market applications.
Satellite communication systems combine features from cellular networks and wireless technologies. New constellations are under development that attempt to provide ubiquitous mobility and internet networks via satellites, ground stations and user terminals. Each link in the supply chain presents challenges for R&D, production and deployment for the components and system development.
This eBook explores the test challenges for 5G and 6G components, beginning with “The Pillars of 5G,” discussing the two parameters that determine network performance: spectral efficiency and energy efficiency. The next article, “Virtual Cable Calibration for OTA Testing of 5G mmWave Devices,” describes over-the-air (OTA) testing methods for mmWave networks. “Design of a Multiple CATR System for Multiple Angles of Arrival Measurement of 5G mmWave Devices,” discusses a novel multiple compact antenna test range (CATR) for testing beamforming systems with scenarios involving multiple angles of arrival. “On-Wafer, Large-Signal Transistor Characterization from 70–110 GHz Using an Optimized Load-Pull Technique,” jointly written by Maury Microwave and Teledyne Technologies, describes a hybrid-active vector receiver load-pull measurement system that can present |Γ| = 1 at the device reference plane up to 110 GHz. Continuing the discussion of sub-THz measurements, “Frequency Scalable Power Control and Active Tuning for Sub-THz Large-Signal Measurements,” written by Vertigo Technologies and Technische Universiteit Delft, describes a novel approach to making large-signal measurements, by expanding the capabilities of conventional sub-THz S-parameter network analyzers to add power control, sweeps and active load-pull. Completing this comprehensive eBook, a reprint of a Rohde & Schwarz educational note by Lawrence Wilson that explains the importance of the signal generator’s performance when measuring receivers.
Direct Digitization at 64 GSPS and Versal AI Processing at Chip Scale
Countering the latest adversarial radar and EW threats requires extremely low-latency responses driven by intelligent, adaptive technology. Addressing this evolving need requires innovation from chip scale to system scale—including powerful system-in-package devices. Learn how Mercury is partnering with the semiconductor industry leaders to deliver trusted microelectronic solutions.
This eBook explores how passive components are contributing to the progress of reducing SWaP, complementing semiconductor integration. Topics covered include reducing RF Circuit SWaP with high K materials and precision thin-film microstrip technology; filter technology options for mmWave applications; compact, low loss switched filter bank using MEMS switches; and using additive manufacturing for Aerospace and Defense components including examples of antennas, amplifiers and filters.
High quality testing requires significantly higher polarisation purity of the system in which the antenna is being tested than of the test object itself. Research to improve polarization performance in a single-reflector CATR has delivered a viable solution in a wide-band dual-polarized conjugate-matched CXR feed.
The term 5G applies to the 5th generation mobile network designed to connect virtually everyone and everything - machines and devices - within the Internet of Things (IoT). However, to incorporate 5G into IoT devices, technological advances are developed as this progress presents potential EMI issues not present in earlier wireless systems.
Getting EMI emissions under control is one of those tasks that R&D engineers do not enjoy doing. EMI must often be taken into consideration as early as the design phase, particularly in the case of power electronics systems with increasing switching speeds of wideband gap semiconductors.
Miniaturization is expanding, as the need for small and complex components increases. Current manufacturing methods such as micro molding have long wait times and are very expensive. This white paper explains how micro 3D printing provides the flexibility of additive manufacturing at a price point that is affordable for production scenarios.
