Amplifiers Give Defense Systems a Boost

This new e-book provides a solid primer on the different types of HPAs and amplifier technologies currently available.

Amplifiers are essential components in defense systems, whether to send radio signals or to energize the pulses needed for radar and electronic-warfare (EW) systems. Amplifier designers chase a somewhat elusive goal of trying to squeeze the highest efficiency possible from their designs, whether using vacuum tubes such as traveling-wave tubes (TWTs) or the latest gallium nitride (GaN) high-power solid-state transistors. For system-level specifiers, making an intelligent choice in a high-power amplifier (HPA) for a defense system benefits from having a solid basic education on the different types of HPAs and amplifier technologies currently available and a great deal of that information can be found in a digital e-book sponsored by MACOM“Amplifiers Give Defense Systems a Boost.”

The e-book is highly focused on defense-related applications rather than commercial wireless communications systems. It covers the types of topics expected for military electronic systems, including the differences between amplifiers processing continuous-wave (CW) and pulsed signals, how solid-state and vacuum-tube amplifiers differ, and an essential exploration of the meaning of amplifier linearity and the type of defense-related applications where it is of extreme importance.

Admittedly, there are many different types of amplifiers that are used within defense-based electronic systems and this e-book is focused only on RF/microwave amplifiers, in both solid-state and tube forms. It does not cover audio amplifiers or any of the more exotic amplifiers involved in capturing and detecting short-duration signals, such as successive-detection log-video amplifiers (SDLVAs). But what it does cover regarding RF/microwave amplifiers is an understanding of achieving high gain and efficiency over the typically broad bandwidths found in EW and electronic-counter-measures (ECM) systems. It reviews the particularly challenging operating conditions in military systems, such as wide temperature ranges, shock, vibration, and humidity, and how both tube and solid-state amplifiers can be designed to maintain consistent performance even when thrust into the most hostile operating conditions.

The e-book serves as an excellent starting point for defense system integrators wanting to know more about the current state of RF/microwave power amplifiers.
