Active Load Pull Active injection load pull, more commonly referred to as active load pull, relies on external sources to inject a signal into the output of the DUT, thereby…
Introduction Extracting a compact transistor model requires several weeks of work, and potentially up to several months when starting from scratch. However, in some cases, the time needed to extract…
Introduction Maury Microwave has more than 60 years of experience in designing, manufacturing, and supporting turnkey measurements solutions. Our expertise includes base station and handset, radar, Wi-Fi, and FEM testing.…
Noise and Noise Figure Noise occurs naturally in any active device or circuit, and limits the minimum levels of useful signals. With a cell phone, for example, it can interfere…
S-Parameters and VNA Calibration
Scattering parameters, or S-parameters, quantify how electrical signals propagate through a linear network. Comprising reflection and transmission coefficients, S-parameters reveal signal behavior at ports, aiding in…
Introduction The term “load pull” consists of varying or “pulling” the load impedance seen by a device-under-test (DUT) while measuring the performance of the DUT. Similarly, “source pull” is Involves…
Introduction Amplifier stability refers to the ability of an amplifier circuit to maintain its desired performance characteristics over time and under varying operating conditions. It is critical to ensure that…
Introduction Vector-receiver load pull is a modern and efficient methodology for load pull measurements. Vector-receiver load pull uses the same automated impedance tuners to tune the impedance presented to the…
Introduction When working with modulated signals, i.e. for 4G, 5G and WLAN applications, for a well controlled linearity behavior of the DUT, the reflection coefficients offered to the DUT should…
