TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • An Introduction To Direction Finding Methodologies

    All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

    This paper discusses the FDTD method to simulate the behavior of plasma materials using Remcom’s XFdtd 3D EM Simulation Software and presents validation in one and three dimensions.

  • Power Consumption Analysis With Specialty DC Power Supplies

    Optimizing power consumption is critical for IoT devices running on small, non-rechargeable batteries. Learn how accurate characterization and smart design can extend device lifespans.

  • Qorvo Biotechnologies Sensor-Based Technology Provides Rapid Reference-Lab Quality Tests At Point-of-Care

    This white paper describes Qorvo Biotechnologies’ Bulk Acoustic Wave (BAW) immunosensor detection platform designed for point-of-care applications and describes analytical and functional sensitivity testing on human Thyroid Stimulating Hormone (hTSH) as an example. The Qorvo Biotechnologies’ platform is targeted to be central lab matched, with the goal of providing clinicians data that will enable quicker decision making across multiple disease states, such as in cardiac and infectious disease segments, where time to result and high performance are critical factors in the patient care workflow.

  • Circuit Models For Plastic Packaged Microwave Diodes

    This paper reports on the measurement and establishment of circuit models for SOT-23 and SOD-323 packaged diodes. Results indicate that the 1.5 nH estimate for the SOT-23 is a useful result, as is 1.2 nH for SOD-323 single packaged diodes. It was also determined that the effective inductance of the SOT-23 may be reduced to approximately 0.4 nH by adding a second bond wire and modifying the microstrip line. Other lead configurations, including parallel bond wires and common cathode configurations, were also studied.

TEST & MEASUREMENT SOLUTIONS

XF leverages the EM principle of superposition to quickly analyze port phase combinations with a single simulation.

The dB-3908 TWT Amplifier (TWTA) is designed to use two wideband, periodic permanent magnet (PPM)-focused TWTs to amplify CW, AM, FM or pulse-modulated signals. The dB-3908 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

The Model 6350S is a small form factor 8-channel A/D & D/A subsystem designed for a variety of applications including high-bandwidth data streaming, waveform signal generators, multimode data acquisition, and other electronic warfare systems. Designed to be integrated into larger systems with minimal design effort, the 6350S delivers the performance and high-channel density of RFSoC in a small, convenient footprint.

The dB-9001 from dB Control is a custom-mounted Instantaneous Frequency Measurement (IFM) unit designed to operate in the C, X, and Ku-band frequency range and provide highly accurate measurements at 100 ns to CW pulse width measurements.

The Si894x is a galvanically isolated delta-sigma modulator which outputs a digital signal proportional to the voltage level at the input. 

Pentek offers the Talon® RTX 2684 as a 26 GHz sentinel intelligent signal scanner recording system. The system provides SIGINT engineers the ability to scan the RF spectrum from 1 GHz to 26 GHz for signals of interest and monitor or record bandwidths up to 500 MHz wide.

dB Control’s family of traveling wave tube amplifiers (TWTAs) features a combined frequency range of 2 to 18 GHz up to 15kW output power. dB Control utilizes our proprietary transformer fabrication, encapsulation and high-voltage potting techniques developed for demanding military applications which results in superior reliability, low cost and ease of maintenance.  Products in this series are ideal for several applications, including: test and measurement, electronic warfare (EW) simulation, RFI/EMI/EMC Testing, electronic countermeasures (ECM), and antenna pattern and radar-cross section measurements.

Radar simulation systems (i.e., RF sources and/or receivers) must perform to an exacting minimum standard if they are to accurately prove the field worthiness of EW systems.
