"S" Series Amplifiers Produce Higher Power, Higher Fidelity Signals For Testing Wireless Output Devices
Mobile network operating costs are driving the requirement for increased infrastructure efficiency, particularly in the final stage RF power amplifier. The venerable Chireix outphasing architecture proposed in 1936 by Henry Chireix has been updated with Gallium Nitride HEMT transistors operating in class E, and shown to deliver class leading efficiency.
Doherty combiner product line covers major communication bands ranging from 700 MHz to 2700 MHz. Each model is optimized for the center frequency of targeted frequency band. However, as new spectrum is being released, the preâdesigned standard models can be tuned in customer applications to meet performance. This document provides guidelines to tune these standard models for offâband applications.
