TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

  • Design And Implementation Of A Miniature X-Band Edge-Coupled Microstrip Bandpass Filter

    Microwave bandpass filters are the fundamental component used in many RF/microwave applications to eliminate interference from signals operating at nearby frequencies. This application note presents a straightforward and largely nonmathematical method for designing an edge-coupled, bandpass filter for X-band operations with a combination of filter synthesis, closed-form edge-coupled transmission-line models, and EM analysis using the Microwave Office circuit simulator within Cadence AWR Design Environment software.

  • Waveform Acquisition Rate And Why It Matters

    Explore key specifications of modern digital oscilloscopes, including often overlooked ones like acquisition rate and blind time, to better understand their importance in oscilloscope applications.

  • 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.

  • Voltage Standing Wave Ratio (VSWR) Explained

    Explore the evolution of VSWR from its humble beginnings in telegraph lines to its vital role in modern RF engineering, illuminating its practical applications and underlying principles.

  • Measurement Of The Phase Between Several Signals

    Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument. 

TEST & MEASUREMENT SOLUTIONS

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 dB-9004 is a custom-mounted Integrated Antenna Digital Control Unit (IADCU). It operates in the C, X and Ku-band frequency range and provides highly accurate RF output (FM, AM and pulse-shape modulated)

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.

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.

Electrostatic discharge testing is utilized worldwide by electronics manufacturers to determine the ESD susceptibility of their devices. It is extremely difficult to estimate the exact cost of ESD loss annually, but it can safely be stated that ESD requires the development and testing of many hardware prototypes and contributes to a high number of warranty claims and loss of consumer confidence if failure occurs in the hands of the customer. Given the high cost in time and materials associated with ESD hardware testing, the ability to simulate the ESD testing process in XFdtd is extremely valuable, allowing engineers to pinpoint locations susceptible to ESD damage and optimize ESD mitigation during the concept and design stage of product development.

Holzworth Instrumentation was founded as a phase noise measurement company. Along the path to phase noise analysis solutions, our high performance building blocks were developed and sold in the form of RF Synthesizers, Phase Detectors, etc. The HA7401A is a Fixed Frequency Phase Noise Analyzer, and the HA7402A is a Phase Noise Measurement Engine.

The series of GORE® VNA microwave/RF test assemblies from W.L. Gore are designed to provide the most precise VNA measurements in laboratory conditions, setting the standard for vector network analyzers (VNAs) through 70 GHz. These test assemblies deliver the highest accuracy and greatest time intervals between recalibrations for many applications, including those with vector network analyzers, critical measurements, and laboratory testing.
