Characterizing high-power GaN devices presents unique challenges that conventional load pull systems often struggle to overcome. As output power approaches the kilowatt level, achieving accurate harmonic impedance control while maintaining measurement integrity, safety, and repeatability becomes increasingly difficult.

Optimizing only the fundamental and second harmonic impedances can leave valuable power amplifier performance untapped. This application note demonstrates how third harmonic load pull enables RF engineers to unlock higher efficiency in GaN power amplifiers by independently tuning source and load impedances through the third harmonic.

As 5G Non-Terrestrial Networks (NTN) evolve from transparent satellite payloads to regenerative architectures with onboard gNB functionality, validating system performance has become increasingly complex. This application note explores how the Maury Microwave ACE9600 Advanced Channel Emulator enables engineers to recreate realistic satellite environments in the lab, helping accelerate development while reducing deployment risk.

Conventional continuous-wave (CW) and single-pulse load pull measurements often fail to capture the dynamic trapping effects that influence the real-world performance of gallium nitride (GaN) transistors. Maury Microwave's MT2000 RF Double Pulse Load Pull methodology addresses this challenge by separating device conditioning from RF measurement, allowing engineers to characterize GaN devices under controlled trapping and thermal conditions that closely resemble actual pulsed operation.

Ampleon announces the B11G4450N91D, a fully integrated dual-section, three-stage 4.4–5.0 GHz Doherty MMIC driver — purpose-built as the macro driver stage in GaN final-dominated macro radio lineups, and designed to give radio architects a cleaner, faster path to lineup linearity. GaN has rightly become the default for macro finals. But the driver stage — that critical link in the signal chain between your DSP and the GaN output — is where lineup linearizability is made or broken.

BlueBird Tech is improving communication performance in challenging frontline conditions. The technology company is introducing new MOXON-R 370 MHz and MOXON-R 430 MHz antennas designed for use in radio communication systems, repeaters, and FPV drones. The new antennas are designed to ensure stable signal transmission, reduce communication losses during operational tasks, and support performance in environments where signal directionality and radio channel quality are critical.

The initiative seeks to accelerate the 5G ecosystem in India to build national capability in support of the country’s ‘Digital India’ Agenda.

There’s an office on Peachtree Street in Midtown Atlanta where a team of engineers are rewriting the rules of wireless communication and the chips that drive our modern world. That team is with Falcomm, a fast-growing fabless semiconductor startup whose products are designed to improve the performance of satellite communications, defense, and consumer hardware.
