High IF Sampling Puts Wideband SDR Within Reach

Multiband radar and electronic warfare (EW) applications put a high value on wideband, high dynamic range, agile spectral monitoring. Increasingly higher sample rate data converters are allowing architecture changes to the radio front end that shrink size, weight, power, and cost (SWaP-C), maintain performance, and evolve toward software programmable common hardware. 

Transient EM/Circuit Co-Simulation In XFdtd: A Closer Look At TVS Diodes For ESD Protection

This paper introduces XFdtd’s transient EM/circuit co-simulation capability, which combines the strength of 3D full-wave electromagnetic simulation with the flexibility of circuit solvers.

Surface-Mount Vs. Through-Hole Technology

There are two main mounting schemes for placing components on a printed circuit board (PCB): through-hole technology (THT) and surface-mount technology (SMT). Given its popularity over the last few decades, it’s no surprise that designers default to SMT, but there are advantages to both schemes that are worth exploring, especially for high-reliability application designs.

Signal Source Level Calibration Using The FSMR3000

The R&S FSMR3000 is a three-in-one instrument incorporating a measurement receiver, a spectrum and signal analyzer, and a phase noise analyzer. This application note demonstrates the use of the measurement receiver to calibrate the signal output level of a signal generator.

Practical Overview Of Antenna Parameters

There are a variety of standardized methods for describing antenna parameters, and this article aims to provide an overview of key antenna parameters and relevant background.

Advantages Of Pan-Type Shielding Vs. Wood Core Panels

Sensitive and accurate measurements are often affected by RF noise (EMI) due to the increase of environmental electromagnetic pollution. Because of this, locations such as communication and data centers, calibration and EMC test facilities, and antenna test ranges for telecom and military systems all require electromagnetic shielding.

An Automated Software Suite For Determining Electrical Characteristics

A suite of software has been created that allows very fast automated analysis of some types of traveling wave tubes. This white paper delves into the design and use of this software for determining the electrical characteristics of traveling wave tubes.

Testing With Mismatch Terminations

Mismatch loads can be used to test amplifiers and help characterize their performance under conditions that might occur in the field. To do so, a mismatch load (or mismatch termination) is used to present a specified VSWR, rather than the usual 1:1 perfect 50-ohm load.

Talking MOSA At The TSOA-ID

TSOA-ID was a success with prominent companies joining representative commands from multiple branches of the U.S. armed forces to demonstrate the latest open architecture advancements that promote interoperability, cost savings, and sustainment.

Video: Optimizing The Performance Of Directed Energy Weapons With Noise Sources

Directed energy weapons (DEW) bring significant advantages to traditional weaponry, but the high optical power required for an effective DEW drives a potentially destructive return loss and reflection that can damage laser sources. Use of a noise source embedded in the weapon’s electronics can spread laser coherence, minimize reflection, protect the laser source, and ultimately improve DEW reliability and performance.
