  1. Understanding Power Divider/Combiner Types And Functionality

    Both resistive type and reactive type power divider/combiners can be used to fan-in or fan-out RF signals. However, both types distribute RF signals in a different fashion. This white paper offers guidelines and considerations for determining a divider/combiner for each application.

  2. 10 Hints For Making Successful Noise Figure Measurements

    Noise figure often characterizes a receiver and how well it can detect weak signals in the presence of self-generated noise. The process of reducing noise figure begins with a solid understanding of the uncertainties in your components, subsystems, and test setups. 

  3. Design Of A Cost-Effective, Hybrid Input-Matched GaN Transistor For S-Band Radar Applications

    This article describes design of a GaN transistor with internal GaAs input matching. The input matching network is designed for the 2.7 – 3.5 GHz frequency range, making the transistor suitable for S-band radar applications.

  4. Introduction To The Waveguide Quick And Tight Connect

    Working in a busy lab sometimes presents the challenge of finding the right tools for every day jobs like the simple mating of two flanges. A simple solution is the quick connect apparatus from SAGE designed for 0.75” circular flanges. 

  5. 5 Things To Consider When Designing Fixed Wireless Access (FWA) Systems

    In the earliest stages of 5G, fixed wireless access (FWA) systems will be used to deliver gigabit internet speeds to homes, apartments, and businesses in a fraction of the time and cost of traditional cable/fiber installations. Like other technological advancements, FWA has its own design challenges and considerations. This article presents five considerations to keep in mind when designing FWA systems.
