Measuring the TRUE NOISE FLOOR of a Cross Correlation Analyzer

This paper outlines how crucial it is to measure and understand the actual noise floor of a phase noise analyzer with a known level of confidence in your data versus relying on calculated noise floor approximations.

Characterizing Active Phased Array Antennas

This application note aims to explain test procedures and give recommendations towards characterization of the relevant parameters for active phased array antennas and their passive subsystem, as often used in applications for Mobile Communication and RADAR.

Airstrip(TM) — an Innovative Transmission Line Technology in Support of Hi-Rel Space Qualified Packaging

Mechanical integration of microwave components often becomes the last step while addressing manufacturing considerations for system-level designs. In many cases, the electrical design is analyzed, boards built, designs reverified, then mechanical engineers fit everything into the final package. This paper shows how component manufacturers can help solve system-level packaging problems using Airstrip technology.

How GaN is Changing the SATCOM RF Front-End

Solid-state technologies such as gallium nitride (GaN) are transforming satellite communications (satcom). GaN’s advantages of high RF power, low DC power consumption, high reliability and smaller size (which reduces system weight) are opening new markets and revolutionizing the RF front-end (RFFE) in existing satcom applications.

The Amplitude Resolution of Digitizers and How it Affects Measurement

Amplitude resolution is a key specification for digitizers. How is this specification matched to the measurement requirement? What are the technical tradeoffs involved in the selection of digitizer amplitude resolution? Having made such a selection what can be done to improve the resolution of the acquired data? Find the answers!

Real-Time Digital Down-Conversion with Equalization

Quality digital down conversion (DDC) is challenging with high-speed time-interleaved analog-to-digital converters (TIADC) due to frequency response mismatches of sub-ADC slices, which cause spurious components. This paper describes a novel method for real-time DDC with slice mismatch equalization.

New Aperture Tuning E-Guide: A Deeper Dive

Aperture tuning is essential in enabling smartphones to operate efficiently over increasing RF frequency bands and support transitions to 5G, but implementation requires in-depth knowledge. In Qorvo’s new e-Guide, learn how to apply this method to your board design with this deep-dive look at aperture tuning.
