Using A Hybrid Coupler In A Microwave Or RF Amplifier Test Setup

Hybrid couplers perform many functions, including splitting and combining signals in amplifiers, switching circuits, and enabling antenna beam-forming networks in applications where power or frequency need to be monitored, leveled, alarmed, and/or controlled.

Can Additive White Gaussian Noise Assess Linearity With Noise Power Ratio?

From testing a system’s response to interference, maximizing the power levels of directed energy weapons via coherence spreading, and securely encrypting sensitive data, AWGN sources are versatile tools that can improve advanced systems.

Wolfspeed RF GaN Meets 5G Demands On PA Design

Designer’s Journey: Navigating The Transition To Versal ACAP

To support ever-increasing computational challenges in radar, engineers must consider new innovative design approaches to meet real-time performance expectations. Utilizing new technology, it's now possible to solve the most advanced radar, cognitive EW, and AI challenges, all on a single board.

Anatomy Of An OCXO - Oven Controlled Crystal Oscillator

An OCXO is a temperature-controlled device that maintains a quartz crystal's constant operating temperature. This prevents changes in the specified frequency due to variations in ambient temperature. This article provides in-depth information on the anatomy of an OCXO and its basic technologies.

AR-50 SATCOM Performance

The AR Modular RF Model AR-50 Booster amplifier provides superior uplink and downlink performance for enhancing UHF satellite communications. Properly setting up the receive path will maximize the link quality and reliability.

Testing With Mismatch Terminations

Mismatch loads can be used to test amplifiers and help characterize their performance under conditions that might occur in the field. To do so, a mismatch load (or mismatch termination) is used to present a specified VSWR, rather than the usual 1:1 perfect 50 ohm load.
