NI AWR DESIGN ENVIRONMENT: Load-Pull Primer for Optimizing PA Performance

Power amplifier (PA) performance under small- and large-signal operating conditions is contingent upon the output impedance match (load). As a result, PA designers must determine the ideal output load for system-driven amplifier requirements such as output power at a given saturated power (compression point), efficiency, and/or linearity.

Design Challenges of Next-Generation AESA Radar

New active electronically-scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and performance requirements are becoming critical and are being addressed through innovative architectures and system capabilities. This white paper examines these technology trends and presents several examples where advances in NI AWR Design Environment are supporting next-generation AESA and phased-array radar development.

NI announces industry’s highest precision PXI source measure unit

NI announced the NI PXIe-4135 source measure unit (SMU) with a measurement sensitivity of 10 fA and voltage output up to 200 V. Engineers can use the NI PXIe-4135 SMU to measure low-current signals and take advantage of the high channel density, fast test throughput and flexibility of NI PXI SMUs for applications such as wafer-level parametric test, materials research and characterization of low-current sensors and ICs.
