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.

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.

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!
