Calculating a Calibration Factor

Technicians and engineers use calibration factors when making measurements; but where do these calibration factors really come from?

Thermal Measurement Methodology of RF Power Amplifiers

This paper offers an overview of Freescale's methodology for thermal measurement of high power RF power amplifiers (RFPAs), including the use of infrared microscopy to accurately determine die temperature at high frequency under RF test conditions, and thermocouple measurements to accurately determine case temperature. It also covers the use of maximum die temperature to calculate a reliable junction-to-case thermal resistance value. A wide range of Freescale's high power RFPAs are available from Richardson RFPD / Arrow RF & Power at www.richardsonrfpd.com.

Modern Architecture Advances Vector Network Analyzer Performance

Modern Vector Network Analyzer (VNA) architectures such as those based on Nonlinear Transmission Line (NLTL) samplers and distributed harmonic generators now offer a beneficial alternative to traditional sampling VNAs. They allow for a simplified architecture and also enable VNAs that are much more cost effective. It is shown that NLTL technology results in miniature VNA reflectometers that provide enhanced performance over broad frequency ranges, and reduced measurement complexity, providing VNA users a unique and compelling solution for their high-frequency measurement needs.
