• SSPA Vs. Tube & TWT Technology: Which Is Best?

  The choice between SSPA and tube amplifiers depends on power and frequency needs. SSPAs offer reliability, efficiency, and compact size, while tubes remain essential for ultra-high-power applications.

• Advantages Of GaN RF Amplifiers With High Peak-To-Average Capability

  Explore how GaN RF amplifiers excel in high peak-to-average capability, offering improved efficiency and linearity over P1dB-rated amplifiers.

• VSWR Conversion To Reflected Power

  VSWR measures how efficiently RF power is transmitted through a load, with high VSWR indicating poor efficiency. Explore VSWR's relation to return loss, reflection coefficient, and mismatch loss.

• Pulse Amplifier Definitions And Terminology

  Understanding pulse amplifiers is key to efficient performance in various applications. Explore essential terminology like duty cycle, pulse rate, and more to aid in optimizing amplifier use.

• RF Test Setup For Measuring Power & Harmonics

  Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

• Amplifier Classification: A vs. AB

  Amplifiers are designed in many ways. We discuss in this application note the differences between the different classifications and what it means with respect to performance. 

• VSWR And Its Effects On Power Amplifiers

  VSWR happens from having an impedance mismatch between a source and a load. VSWR is not a hard concept to grasp, but its effects on the instrumentation can be more difficult to realize. 

• Power Indication & Relative Accuracy In Amplifiers

  The purpose and scope of this document is to explain amplifier power indication (metering) and typical variations associated with frequency sensitivity and bandwidth. Exodus amplifiers with our display/controller provide many monitoring and control functions.
