TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

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.
How To Test USB Power Delivery Over Type-C
USB Type-C compliance test standards are more complex due to higher data transmission speeds and more power. Successful testing requires accurate and compliant test instruments, software, and fixtures.
Field Probe Correction Factors
To better achieve accurate field level measurements, it is helpful to have an understanding of field probe calibrations, the factors generated, and what’s presented as data during testing. This application note presents how to utilize the factors presented for inclusion into test data, how to generate composite measurements, and why calibrations are performed at selected frequencies.
RF Amplifier Output Voltage, Current, Power, And Impedance Relationship
How much output voltage, current, and power can you expect from your amplifier? In rare cases, this can be answered by applying Ohm’s law, assuming that the net power or power delivered to the load is the rated power output of the amplifier. In most cases, practical issues such as VSWR and forward power concerns must be considered before applying Ohm’s law. This application note addresses this issue and discusses an approach to be used that applies actual test data when calculating output parameters.
eUICC Profile Handling
This application note describes the eUICC compliance and remote eUICC provisioning test solution based on R&S CMW500/CMW290 and COMPRION eUICC Profile Manager software tool with focus on M2M devices.

TEST & MEASUREMENT SOLUTIONS

Microwave And RF Test Assemblies: GORE® PHASEFLEX® Series

The GORE® PHASEFLEX® Series offers the smallest, lightest, internally ruggedized microwave/RF test assemblies for high density interconnection in RF and uW modular applications as well as in high speed digital testing. These assemblies feature ON cable construction and provide consistent, repeatable measurements with electrical performance up to 18, 26.5, 40, or 50 GHz.

8 – 12 GHz, 10 W GaN SPDT Switch: QPC2040

Qorvo introduces the QPC2040 single-pole, double-throw (SPDT) switch operating within the 8 – 12 GHz frequency range for commercial and military radar, communications, electronic warfare, test instrumentation, and other general purpose applications. The switch typically supports 10 W input power handling at control voltages of 0/−2 V for both CW and pulsed RF operations.

TWT Amplifier: dB-3907

The dB-3907 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-3907 offers higher saturated output power and improved harmonic performance when compared to a single TWT approach.

Electrostatic Discharge (ESD) Testing Simulation

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.

Integrated Stabilized RF Source: dB-9003, dB-9005

The dB-9003 and dB-9005 from dB Control are custom-mounted Integrated Stabilized RF Sources (ISRFS) designed to operate in the I and Ka-band frequency range. Both products feature high accuracy and a wide temperature operating range. They can be controlled and set up with a digital port. The units are packaged in a custom configuration with conduction cooling.

Integrated Antenna Digital Control Unit: dB-9004

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)
