5 Steps To Selecting The Right RF Power Amplifier
By Jason Kovatch, AR Modular RF

You need an RF power amplifier. You may even have decided on a power level that you think will meet your needs. With so many variations in price, size, and efficiency for amplifiers that are all rated at the same number of Watts, many RF amplifier purchasers are unhappy with their selection.

Multi-Beam Monopulse Radar For Airborne Sense And Avoid System
By Ashok Gorwara and Pavlo Molchanov, Planar Monolithics Industries

The next step in passive monopulse direction finders is development of a multi-beam monopulse radar for airborne-based sense and avoid (ABSAA) systems. This concept consists of a multi-beam monopulse radar with an array of directional antennas, positioned on a small aircraft or a UAS.

How New DAC Technologies Are Changing Radar & EW Signal Generation
By Christopher Skach and Sahand Noorizadeh, Tektronix

Application areas in radar and EW system, sub-system, assembly, and component design work have complex signal generation needs, leading to the use of custom-designed solutions for analog signal generation that are expensive and inflexible compared to COTS alternatives.

Mitigating Phase Noise From Vibration In Air Traffic Control And EW Radar Systems
By Smiths Connectors

Internal phase noise effects generally take the form of impurities or nonidealities in oscillator circuits and resonators. External effects can be caused by vibration by certain components and circuits. 

Using FEKO To Calculate Radar Cross Section Of Aircrafts With Engine Inlets

Asymptotic methods are the preferred method for calculating the radar cross section (RCS) of targets like aircrafts since the main parts of the target are more than an order of magnitude larger than the wavelength. 

Flying Aircraft Radar Signature Acquisition And Determination: FARAD Brochure

The Flying Aircraft Radar Signature Acquisition and Determination (FARAD) system is a flexible, customizable, and expandable radar system designed to perform short, dynamic radar cross section (RCS) measurements of stealth-like flying targets.

Care And Handling Of Cable Assemblies And Connectors
By Bill Pote, MegaPhase

Cable assemblies are critical to obtaining correct test results and signal integrity in many applications. Proper care and handling of cable assemblies and connector interfaces is critical for insuring accurate operation. 

High-Power And High-Efficiency Ka-Band Power Amplifier
By Salah Din, Mike Wojtowicz, and Mansoor Siddiqui, Northrop Grumman

Ka band is used in many applications, including electronic warfare, where the most demanding cost and performance requirements are imposed on the transmitter MMICs, which must have good power added efficiency (PAE), output power (Pout), die size (power density), and reliability.
